I loved this movie so so much. >.< Originally I was drawn to it because of Paddy Considine (HUGE fan of the Cornetto trilogy with Simon Pegg, Nick Frost and Edgar Wright, where he usually has a role.)
As far as zombie movies go , I thought it had a neat twist on the genre. (Thought it did remind me a lot of 'the last of us' with the plants/spores zombies ect)
I think the author of the original book has other titles under their name, don't quote me though, but they may adapt well to movie also ^.^
