Well, I finally got to see it, and I had high hopes after the trailers and the reviews, especially the one star Daily Mail one, that convinced me it was going to be really good fun, and...
It was epic stuff!
SO pleased I bothered the hour and half's travel to get to a cinema that showed it ( had a couple of free tickets to use up too, so it balanced out the travel.)
Honestly, if you're not offended by some..fairly heavy violence, tho it's nothing like Saw or the like, mainly shootings, stabbings, and full on explosions of people, then give it a go!
I was impressed by how much empathy I had for the characters too, normally any child actor makes me want to go on a killing spree within 30 seconds of them appearing, but she did such a fine job of being utterly mental, and yet entirely Big Daddy's little girl, and just a regular kid... in most ways.
Also, there was a trailer for...someone vs the world, it looked like some guy has to defeat a girl's 7 ex boyfriends, but they're all real life versions of videogame characters, when I saw 'by the director of shaun of the dead and hot fuzz' I was sold, and it looks stupidly good fun too!
