Good start, but then it gets ruined

It isn't all that great, actually. Really cheesy and very predicable of how certain scenes are gonna turn play out. However, I guess that's the charm of it all, because I would consider this one of my guilty pleasures.

The thing I enjoyed most about the film is the fact that it doesn't shy away from being a super-sized-cliche;

A great movie, one of the best of this year. There was a bit of confusion at one point in the plot, but nothing serious.
