Vampire's Kiss - Trashy but amusing late 80s "dark comedy" with Nicolas Cage (still very young, though it was never easy to tell how old Cage is or was) doing his first gruesome load of overacting, to hilarious effect. "I'm a vampiya!!! I'm a vampiya!!! I'm a vampiya!!! I'm a vampiya!!!"
Gymkata - Ebert trashed this once. Every once in awhile you'll see a reference to it.
Fantastic Four 1994 - Saw clips of it. Used to amusing effect in Arrested Development season 4, for a cute obscure reference. Hilariously the new F4 movies aren't much more loved than this one.
Troll 2 - Duh, of course, Make sure to watch Best Worst Movie too.
So there IS someone out there cataloguing all the godawful Star Wars/Flash Gordon-inspired ripoffs from 1980? What was up with that year?
Chopping Mall - Only know the scene where a robot shooting lasers makes a girl's head explode!!
