I know it's way too late to comment but...

Rating: 2/10 (12 April 2005)

Just in case anyone is tempted to rent the DVD and spend 2 hours watching this inexplicably highly-acclaimed movie? Do yourself a favor and rent "Heat" again! I like Michael Mann movies...I heard a lot of good buzz about this one. None of the buzz is warranted. I think critics get all agog whenever a comedian does a serious role or something, or maybe Foxx is just riding a wave, but in any case everything about this movie is disappointing. Disappointing, boring, implausible - these are deserving terms for this movie. It's not "junk", it's just...everything I just said.
First, the acting is NOT that great. The single scene where Foxx has to re-retrieve the memory chip is notably good. Besides that there's no material here for an actor to display his/her chops. The very PREMISE falls so many times - the cabbie not simply running off from the start, the ending that is SO GIVEN AWAY by Foxx's first fare, the cops not arresting/detaining the two upon being stopped after the first hit, the fact that Cruise's character doesn't simply kill Foxx off once the latter destroys his entire briefcase. All insanely unbelievable.
But...assuming that you can "suspend disbelief" for all of this, just to wait for the payoff ending? Nothing! Cruise's character is this remarkably efficient assassin throughout - deadly accuracy, ability to focus on his target in chaos (the club scene near the end) - all that goes down the tubes as he guns for the last victim (Foxx's initial fare). I mean, one chick in an otherwise empty building ELUDES him?!?! WTF! And then in the very end, Cruise gets a heart, or loses heart, or..something! And he spouts that cheesy line from the beginning of the film and....expires. Doesn't even die, just expires.
And the viewer looks at his watch and realizes two hours have passed with nothing to show for it. Not even worth water-cooler talk.
