Drive-in Trailers: Hospital Horror

I've been fortunate enough to never need surgery, but I think a vast majority of us have had to make a few trips to the hospital for one reason or another, and it's never fun. But imagine how much worse it would be if you were dealing with serial killers, ghosts, or just plain crazy demons with their own idea of 'medicine'. This week I'd like to focus on hospital horror trailers, and if you find yourself sitting at home right now trying to fight a nasty case of the flu...please, get well soon.
