This is certainly an entertaining movie, what with all the ridiculous death scenes and Gerard Butler's total badassism, but that's pretty much it for this flick. It does hurl the "the justice system is corrupt!" message at you pretty much continually, which I guess is a good thing to do, ignoring the fact that subtlety is thrown out the window. And when comes the time to explain how the guy has been pulling off everything during the movie, the writers have backed themselves into such a tight corner that the answer is just as ridiculous and over the top as everything else before it.
It's worth watching as entertainment, but it still comes off as a failed attempt at being poetic.
In a sentence:
Cool acting from Butler, intense death scenes, good cinematography, but just... silly.
