This must've been the worst movie I've seen in several years. And I've seen quite a few strong contenders.
How could an actor like Mads Mikkelsen read this script and actually decide to do the film? It's some of the worst screenwriting I've ever seen. Cliché upon cliché. Very hard-to-believe actions (even for a shallow action movie, this just will not stand). Meaningless, uninspired dialogue. Shallow characters. Horrific acting (can someone tell me why Shia Lebeouf is considered a decent actor anyway?). What a joke. Wow. Just, wow.
I was gonna say "well, I've seen worse" but I'm trying really hard to think of a comedy-sequel that was less funny than this. Probably Hangover 2, though they're definitely in the same league.
Brick had one or two funny moments. That was about it for me. The story was about 30 minutes too long, and the jokes were mainly rehashes from the characteristics we've known from the previous film.
I don't see how people even try to compare this to the original which was superior in every single aspect.
If you love Lost In Translation, this is something to check out. It shows Sofia Coppola coping with lowbudget movie-making, and a small filmcrew working very hard to make it all work.
Meanwhile Bill Murray steals the show with hilarious encounters with Japanese citizens, and doing some great ad-libs that ended up in the movie (of which I didn't even know they were ad-libs).
