Got my hands on a few older flicks I missed (or was too young to see) the first time around and will be checking them out over the weekend:
American Nightmare (1983)
House on Sorority Row
Last Days of Man on Earth (aka, The Final Programme). I actually did see this on cable, way, way back around '81 or so (when I was just a wee nard all of 9 or 10 years old), but I remember almost nothing about it except some sex scenes and a guy walking off at the end looking like some kind of missing link.
I'll also be checking out The Last Exorcism, which I avoided due to seeing Eli Roth's name attached (even if his involvement was minimal) but I noticed a couple folks here have said some good things, so...
