Gangster Squad.
I had no intention of seeing this film, but a few other friends wanted to see it and half of us had the Orange Wednesday deal (2 for 1). Unfortunately, to take advantage of the deal, you can't pre-book, and none of the guys thought to get tickets ahead of time, so we wound up in the front row. You may have seen my friend's tweet that his neck was as strained as the dialogue. That said, it's not a contributing factor to why I disliked the film.
Put simply, it's a big dumb action film dressed up in a sharp 1940s suit. Not even Ryan Gosling and the few well-done comical beats (as you might expect from the director of Zombieland) can redeem this one. It makes The Untouchables - an inescapable comparison - look like high art. It's got a squad of token characters, with on-the-nose motivations and backgrounds, and is bursting with every cliche imaginable. The 'finale' had me cringing nearly the whole time. And when it has a crescendo that builds to the final punch...
Doesn't help that I can't stand Sean Penn either.
