Firstly, this is not a film to take seriously. If your after a gripping, suspensefull horror, look elsewhere.
Think Shawn of the dead mixed with Lesbian Vampire Killers, with a small dash of 28 days later. A "lads" horror comedy if you like. Very sexsist, very gory and full of Danny Dyers one liners. Providing your not easily offended and know what to expect, this is a film that can be enjoyed by both men and women alike.
Also, a special mention to Noel Clarke (of Adulthood fame) who is a great addition to the cast. A true star in his own right.
One small gripe (and it is only one), Danny Dyers "geezer" like persona can become a tad annoying as the film progresses. However, he never fails to deliver and provides the bulk of the humour.
Switch off your brain, sit back and enjoy the film for what it is. A laugh.
