This film started out great! In fact, I thought it was brilliant until it got to about 1/3 of the way through and then it plain nose-dived.

So some loser is framed for murder and he goes to prison, where he gets treated like the child-rapist is was convicted to be. He escapes and... the film went full retard (never go full retard!), right down to the lead turning Daredevil and the villain painfully over-acting his nervous breakdown.
Cliches abound, all plausability is stretched past breaking point, the plot becomes muddled... sigh, I really can't express how awful and stupid such a superb concept becomes when the writers - or whoever - simply cannot plot coherently.

Still, it gets a 4 for the great idea and an excellent first act... but honestly, once he breaks out of prison (maybe 30 minutes in), you'd be better off hitting the stop button and imagining your own ending.
