Beetlejuice (1988)

I would not, and neither would most, call this a horror film as such; it's more a dark, comic, typical Tim Burton film with eerie elements to it. However, I would say it is a truly brilliant creation - I've been watching it since I was a kid. A couple, who die in a car crash, attempt to scare off the people occupying their house with the help of another ghost, Beetlejuice, who claims to be able to 'exorcise' the living. This film gives a funny but dark take on what happens when we die - and Alec Baldwin looks young and thin! It's won an oscar and a load of other awards so I guess it's not just me that thinks it's awesome!
