The Evil Dead

If you go down to the woods today, you might just run into some ancient demons(well if you play the tape and summon the bloody wee beasties up that is)

With a plot that was probably written on the back of a packet of cigarettes this film shouldn't work, yet the mix of gore and splatter over the top effects and often out an out dark comedy makes this one a gem of a film. 

Several versions of this are out - often cut by a few seconds here or there - although the original uncut film has been released and is now thankfully widely available.

Much like American remakes, the snip of the prod nose censor is one thing is dislike. Still the great and the not so good worked themselves up quite a bit over this film, calling it a video nasty and such like. Of course all that did was ensure everyone wanted to see the film.

Some of the special effects have sadly not dated well, but still an absolute classic of horror that every fan of splatter films must own(just look up an uncut version Anchor Bay have one on general release.)
