First, it's a movie about zombies and it's English, so don't go in expecting some grandiose academy award winners. What we have is a film that is meant to be watched and enjoyed. It's purpose is to entertain us with zombies, gore, and the best type of dry Brit humor one can find. A job it accomplishes rather nicely.
It never takes itself seriously but doesn't go full on to cheeky parody mode either. I have to agree that like Shaun of the Dead or Tucker & DAle Vs Evil, this one has successfully blended a great comedy with a good horror flick. though I'll warn it's more about the good gore one finds rather than scares.
By far the strongest actor would be Alan Ford who fills the character role of "Grandad" brilliantly as the cantankerous grandfather of the two leads and the caretaker of an old folks home. He has some of the best lines- most of which you simply don't expect or at least won't know what the heck is gonna be said next. right from the get go with opening credits you have the idea it's gonna be a fun, somewhat satirical ride and indeed it is. In all, the plot isn't that much of a stretch(it's zombies) but the actors and director make it work. it has a decent music score too. after viewing it may not be in some horror fan's top fav list, but it will certainly not disappoint. (also if you like crass British slang you'll like this movie)
