Watched all these recently:
Now You See Me - having recently watched TWF's recommendations of 'The Prestige' and 'The Illusionist', thought I'd watch this one. Turns out to be pretty decent, just don't take it too seriously and you should get on with it
World War Z - Alright, in honesty! Nothing refreshing, but not a bad effort at a typical zombie movie. Helps if you like Brad Pitt.
The World's End - From my favourite acting duo. My least favourite out the 3 films, but, I do love them a lot. Overall it was quite enjoyable, quite mellow, with some funny moments, and it's a bit different to the other 2.
Pain and Gain - Excellent IMO. The Rock actually does some good acting in this! Based on a true story, very enjoyable. Lots of action and funny moments, with a serious dark side running all through to the ending.
Grown Ups 2 - Pile of shit in honesty. We watched number 1 and 2 straight after each other, I would say the 2nd is worse than the first. I still laughed but don't take that as much of a compliment.
Kick Ass 2 - Yeah, pretty good. Probably all to be expected, but story carries on well, some funny moments, some lovely gorey action as per the first movie.
