In the adaptation, Colin Farrell and Jamie Foxx fill the classic roles of Sonny Crockett and Ricardo Tubbs respectively. As partners, this aspect of the story provides at least a basis for further exploring the notions of trust and deceit at the film’s core. When Tubbs says to Crockett “I would never doubt you,” it represents the reality of their lives, the only tangible aspect of their profession. It is a point, however, glossed over somewhat and certainly not capitalized upon as it could have been. A thorough examination of their relationship is not needed, but an understanding of consequence of that relationship is certainly a must, and it is really nowhere to be found, even within the confines of subtext (something at which Mann has proven himself an expert time and again).

The nuts-and-bolts plot of the film plays itself out seemingly as an expansion of one of the series’ various faceless scenarios. After a former informant compromises an FBI undercover operation, Crockett and Tubbs, being a part of the Miami-Dade Police Force and existing outside the confines of any possible leak, are recruited by the Bureau to investigate further – and deep undercover.

There is then an assortment of expected character types, from the introverted, consistently pondering drug kingpin (Lois Tosar), to the weasel-ish middle man who smells something fishy (a rather diabolically entertaining John Ortiz), to, of course, the tough-as-nails businesswoman-slash-kingpin girlfriend (Gong Li). This triumvirate of typicality is painfully derivative from the get-go, but we’ve seen Mann take the cliché and turn it into stylistic substance before in “Collateral,” so assuredly one could expect as much once more. Sadly, no such turn of events is in store.

The film is truly owned by Colin Farrell, regardless of whose name appears first on the poster and which Oscar-winning actor whined for more prominent status on the film’s payroll. Farrell in fact acts Foxx off the screen for the most part, though Tubbs is admittedly an awkwardly designed character. He boasts a quasi-romance that is ill-defined with fellow teammate Trudy Joplin (Naomie Harris), and he turns to comedic sensibilities a bit too often in his “undercover” guise, so much so that, were I Crockett, I’d demand a less obvious partner for fear of being gutted by a suspicious drug lord. No matter how rewarding the one-liners might be on one hand, on the other, they simply represent one more wrinkled aspect of the piece that could have used some ironing.

Farrell, however, lives and breathes inside Crockett in perhaps his best performance yet – though his accent does slip at times from the Bronx to the south, oddly enough. He gives us the complexities of the character that are not found on the page (unlike Foxx), and even when the forced romance with Gong Li’s Isabella rears its trying head, we believe the loneliness and the despair that drives Crockett to seek out that connection. At the very same time, we can sense him reciting the words of Neil McCauley in his head: “Don’t let yourself get attached to anything you are not willing to walk out on in thirty seconds flat if you feel the heat around the corner.” Even still, it is a different idea at work here, one about longing and necessity more so than discipline and detachment.

Li, however, seems forever uncomfortable in a position we are meant to believe is some saving grace for her. She shares the solitude of Crockett, the loneliness. That is their common denominator, and the single thread with which we are to buy this romance. But she does not sell that notion in the slightest. She seems almost lost in her character’s dialogue and motives. Who is this woman? Beyond a random anecdote about her mother – a lone wolf in her own right, it seems – from whence does Isabella come? We do not know.

Nor do we know much about Crockett. However, even when he is given the interesting task of peering longingly out of a window in the film’s first act, we know there is something there. But even then, why? What – even possibly – haunts this man? Did his career create a rift between himself and another lover? Various other lovers? Does he pursue a life of lies and deception undercover to escape the realities of his own anonymity? What are the realities of his anonymity? These themes never even threaten exploration, and the sound of air rapidly filling the space vacated by such dearly departed intricacies of character is all we can hear indeed.

Elsewhere in the cast, John Ortiz weaves a truly villainous serpent, fit with hypnotic syntax and devilish grins. Though his character is painfully ordinary, Ortiz makes him eminently watchable – as does Tom Towles as a despicable and somewhat terrifying man who chews gum as if it were his sole purpose on earth. Furthermore, Barry Shabaka Henley, always a delight, provides a steadfast Lieutenant, a serious and driven man to trust. Even when his dialogue seems forced, we still believe every syllable.

The rest of the cast is somewhat anonymous by Michael Mann’s standards. Here is a director who has always been adept at filling the frame with a variety of characters, but however minute their bearing on the story, there was always dimension to be found.

Domenick Lombardozzi (you’ll recognize him from a cameo performance in this season of “Entourage”), Elizabeth Rodriguez (“ER”), Harris (“28 Days Later”), Tosar (“Los Lunes al Sol”) and Ciarán Hinds (“Munich”) fill their positions by the book. However, the loss of substance in the peripheral cast is felt most painfully in the fact that Justin Theroux (“Mulholland Drive”) is just there, taking up space. Theroux is one of the most striking and interesting actors of the underrated lot today – potential movie star material. A Michael Mann film should be his playground, yet there he is, forever an afterthought.

All of that said, John Hawkes’s oh-so-brief work in the film’s opening scenes soaks up the role of Alonzo for all it is worth. It is rare to understand a character so thoroughly in such a brief amount of time, and with such a consistency of emotion and complexity. You’ll recognize Hawkes from last year’s “Me and You and Everyone We Know” and television’s “Deadwood.”

All this talk of the varied cast (however clichéd) has left me little time to fully discuss the technical aspects of the film, all a step down from the vibrant “Collateral,” yet still a move in the right direction for digital cinema.

Dion Beebe’s lensing still lacks the thematic composition of Mann’s work with Dante Spinotti in years past, and even of Emmanuel Lubezki on the underrated “Ali.” However, the juxtaposition of the imagery by way of William Goldenberg’s and Paul Rubell’s film editing keeps the pacing relentless and creative, as always.

Additionally, it seems as if Mann has found a new musical muse in Audioslave, the remnants of a singerless Rage Against the Machine with Soundgarden’s Chris Cornell at the mic. Mann has always been a fan of Moby (and seemingly still is, given the inclusion of “Anthem” and “One of These Mornings”), but this is the second time Audioslave has been featured so prominently in one of his films (following the potent usage of “Shadow on the Sun” in “Collateral”). The band contributes two new and appealing songs to the film’s soundtrack, but sadly, said soundtrack feels like a mix CD, a new track every other minute. Mann is a master of aural atmospherics, and the sparse score even recalls the majesty of Elliot Goldenthal’s work on “Heat” at times. However, such things seem entirely rushed and thoughtless in his latest effort.

The question with which one is left after viewing “Miami Vice” is “Why did Michael Mann want to make this film?” Was it the desire to dig into the theme of lies through the world of undercover policing, as has been reported? Likely. But if so, where is the passion we’ve come to expect of his work when he is so focused, so driven? Where is the touch of humanity that seems almost organic? Why does this script feel as if Syd Field deserves a credit? Why such typicality? These all become rhetorical questions in the final analysis, but as filmgoers, we will be quite the lucky when Mann decides to leave the desire for romp behind and tackles much more personal and engaging fare once again.

“Miami Vice” is anything but personal. It is a – sometimes – gratuitously violent (Verhoeven-level), generally by the numbers actioner with elements of depth and promises of texture that are more often teased than explored. It is vacant and even elementary on as many levels as it hopes to be poignant and thematically authoritative, and though it concludes with the emotional tinge that recalls Michael Mann cinema, it fails to reach the bar he has set for himself. It is a high bar indeed. Perhaps he is doomed to chase it forever.
