'Drag Me To Hell' (2009) directed by Sam Raimi

This is such an outrageously fun movie, it's the film equivalent of a really good theme park ghost train. Harking back to Raimi's earlier work, this film is full of great scares and really illustrates that Raimi is a master of the horror genre. It's got all the necessary elements; a gypsy witch, a soul-eating demon straight from the depths of hell and all manner of ghosts, ghouls and a more than adequate amount of gruesome bodily fluids. While keeping you on the edge of the seat, this film also has a really sharp sense of humour and doesn't take itself too seriously at all. It has some hilariously quotable lines and the twist ending, while being signposted early, is still delivered in such a way that it really hits you.
