It's all about the SLEEPING BAGS.
I'm not sure what the worst movie I've ever seen is, but the worst horror movie I've ever seen is without a doubt "The Video Dead". I'm going to get a copy of it and do a write-up about it sometime on I-Mockery. The only thing that makes people want to see it is because the box art for the movie looks like it came straight off of an Iron Maiden album.
