1. Sly Stalone's pretensions. Why take a perfectly good shoot 'em up and try to make it 'weighty' with some kind pathos and emotional heft? I appreciate the fact that Charisma Carpenter is age appropriate as a love interest for a graying bad-ass, but...WHY BOTHER? You are wasting my time with plot points no one could possibly invest in, and this popcorn ain't gonna eat itself. Also, why have Jet Li if he doesn't get a chance to kick ass?
2. If you are going to make a live action Sorcerer's Apprentice, if you don't plan on using or clearing THE music, you DON'T HAVE A MOVIE. Just shut her down right there.
3. Like there isn't enough nerd cred to break Scott Pilgrim into two movies. Is there anyone who wouldn't have like more Scott Pilgrim?
4. The marketing campaign for The American. For those that haven't seen it, it's basically a Leone Western, set in Italy. It's not George Clooney: Badass. Though Clooney is a badass, this isn't Identità Bourne, it's Unforgiven in small town Italy. Also, the final shot is a teensy bit on the nose, not quite as bad as "The Departed" but up that alley.
5. Speaking of endings that pissed me right off; Inception. Spolier alert and all that, but I call bullshit on a transparently, insultingly blatant message from Chris Nolan saying "TALK ABOUT MY MOVIE!!!!"
Look, I'm fine with ambiguity and think it was perfectly acceptable in this story. But much like a restaurant too-visibly angling for a 4-star review, the plea for memorability (and one would assume, Oscar's) is so evident as to be off-putting. In fact after being in a constant state of "this is awesome" all through the film, I left the theater frustrated and angered. I'm sure there are dozens and dozens of ways Nolan could have ended the film, but picking the one which caused about 75% of the audience with whom I saw it to audibly groan was probably the wrong answer.
Next film which has the potential to disappoint me horribly? "The Town".
