For those of you that crave mindless gore (with plenty of braaaaains...), I have to recommend The Dead Next Door. I remember it being utterly redundant, but if one can bear the ultra-low budget, the special effects are very impressive. With that said, once again, the acting and plot of the film are long and far from the best. It's an interesting addition to the collection, though.
I've always also been partial to Elias Mehrige's BEGOTTEN, also. That's for you David Lynch-surrealist junkies out there.
