I love a good horror but there are so few of them these days, or maybe I'm just getting harder to scare! However I did happen upon one the other day, 'The Fourth Kind'. Won't say too much for fear of spoiling it for others but it was really creepy and suspenseful - my poor little dog who was sat on my lap at the time found herself gripped a bit too firmly at times!!

Which films genuinely scare you and why?
