While the title does have more than one meaning, there is not that much depth in the characters. Of course you do know what the characters have to do to get out of their "rhythm". The question being, if they all really want to do that. Apart from the very straightforward story, some questions about morality (though not well played), the actors might be the weakest point here. Especially our main guy cannot convey any feeling as hard as he may be trying. But he's young so maybe he'll come around one day.
Amanda Crew tries, but doesn't have that interesting of a character either. Plus her "pivotal" scene does not convince entirely. Not to mention that she is too often passive than she should have been. Finally the third character might be the most interesting, but even he fails to bring the movie around on his own. Interesting, but nothing special (the twist at the end not really helping either)
