There were a few early 80's horror movies that were cheesy, in fact dozens of them! - Parasite, Trolls, the sort of thing you would see trailers of every time you rented a video. Low budget, badly written, and a cast you've never heard off

- not like these days when they spend a fortune on a movie and get a good cast, then still make it cheesy as hell.
My favorites were the 'last man on earth' ones, where you had one survivor looking to repopulate the world after some nuclear war or whatever - Fallout3 reminds me of them a lot, anyone remember the names of those films?. I still watch this stuff, even just to have a laugh at it - if you can rip into a film and pee yourself laughing at it, then that makes it just as worthy as the next, previous, and any Jack Black comedy regurgitation.
