Kill List is one of the greatest horror movies of recent years if not all time. That movie sticks with you. (A Field in England is an interesting follow-up movie from the same director but nowhere near as strong.)
The one that I'm not sure Patrick's seen is Berberian Sound Studio which is a fantastic and subtle piece of meta-horror. Highly recommended.
I was just lamenting not buying the original (mainly because I would never be able to wear it in public), so this is a great tribute shirt. Still not for public use but I think Ryan would appreciate a lounging around shirt for private gaming time.
Edit: I would also love to see the entire crowd in these shirts at the next GB panel...
I've found the best way to get through World 2 is to use bombs liberally to head downwards quickly. The climbing gloves on World 3 allow you to scale the side of the level, avoiding practically all the dangers.
