I love zombie films and the first two are total classics.
This film is very different. Likely not what most people expect, hence their huge criticism of it.
**SPOILER**
What surprises me in the reviews I read is that hardly anyone seems to get the ending, which left me chuckling with the irony.
Tracksuit wearing, blinged up caricature types looking like Jimmy Saville (hugely infamous Brit paedophile) kill off all the zombies in power rangers style. And the lead one says 'My name's Jimmy - let's be pals'. This is the darkest line of the whole film - to me it signifies that the young hero just escaped the frying pan and now fell into the fire!
