I'm gonna stir things up a bit and say "really?"
Admittedly it is good for a sunday afternoon with a hangover but the plot is a little bit daft, predictable and all in all a bit weak! It might just be me but i prefer something that makes you think a bit more rather than something that opens really well and then the director realised he was gonna over run so killed a few guys, blew a few things up and everyone lived happily ever after!
