I thought I would add my thoughts on world war Z...
Having read the book, I wasn't looking forward to this, due to the trailer appearing to be nothing like it. And, it has very little in common, however I actually found I enjoyed it!
Acting was decent (except for those annoying daughters-someone infect them already!), visual effects often impressive, and the pace was always high speed. There was the odd decent jump, and several scenes stood out- the Philadelphia opening was fairly intense. Fans of the book will pick up on a few similarities and references, however I will warn you that the story and style of the book are all but gone.
There is one problem which has stuck with me. The film feels like three different sections, with very different takes. The singular, blurry cgi enhanced zombies in act 1, the swarm of flailing arms in act 2, and the generally slow make-up zombies. It creates quite a stark contrast, which is quite odd.
Overall, I would give it an 8/10. It has its flaws, but its not too shabby, not at all.
