Over-directed (pointless virtuosic touches that add nothing to what's happening on screen with the plot or characters), over-scored (save me from the freakin' metal Irish jig and the Stones, both heard twice in this thing), over-edited (the movie is awkward: scenes flow neither internally or into each other) and over-acted by Jack Nicholson (so far beyond the point of self-parody that it ceases to be funny), this horrid, horrid film is filled with two dimensional characters (except for Madolyn, the worst psychiatrist who never lived, who lacks even a second dimension) and more profanity and violence than you can shake a stick at.
Really, I've never been a Scorsese fan, but this movie owes any praise it deserves for its twisty, turny plot to whatever was left over from the original "Infernal Affairs". Yes, in case you didn't know, this movie is a remake of a far superior Hong Kong film.
As with "Dreamgirls", another inexplicably over-praised 2006 release, there's just no denying the nudity of this emperor. Tedious where it should be crackling and dull when it should be suspenseful, Marty and crew have made a nasty cinematic mess that really does not deserve the all-too-predictable praise that's been heaped on it. "Instant classic", "best film of the year", etc...
I'm sorry, but the technical competency of the filmmakers is questionable and the emotional impact of the story is zip. By the last few minutes, as blowing a person's brains on the wall is becoming more of a cliché than you would ever think possible, I found myself hoping that some deus ex machina would descend from the sky and just kill everyone so it would just be f**king over already.
