The best horror film of the eighties This is a gem, it really is. Alternately amusing and horrific - John Landis plays our emotions like a fiddle here. He is pulling all the strings and we are uncertain as to which string he is going to pull next. From the eerie Yorkshire countryside of the opening scenes through David's awful nightmares in hospital to amusing zombie chit chat and finally the climactic slaughter in London - this film never lets up. How many films will you find Kermit the frog sharing a scene with throat slicing, machine gun wielding mutants dressed as Nazis?
