Messi_is_Messiah: I wonder if Slither counts? It had a 12million budget but everything about it is classy b horror. definitely recommend.
Slither definitely counts! Thank you for reminding me, I was looking for Slither when I came across
Splinter, somehow. I watched Splinter, I loved it (especially because it's a post-2000 horror movie that basically relies on practical special effects/prosthetics instead of CG), and in the meanwhile forgot all about Slither.
I really should thank you all for your kind suggestions; obviously, I could have just gone to a b-/c-/z-/psychotronic-movie website, but this way I think we're sharing with each other and every single one of us participating on this thread benefits from it. I now have two pages of suggestions, and I plan on watching a few tonight.
IAmSinistar: Glad to hear it! Jacob's Ladder is one of my favourites as well, and deserves viewing from anyone who appreciates complex horror. I've also long suspected that it influenced aspects of the Silent Hill games in some part.
EDIT: Just noticed you added Isolation to one of your earlier posts. I really enjoyed that one too.
Jacob's Ladder sure was an inspiration to Silent Hill developers. They say it quite clearly on the Silent Hill 2 DVD which, fortunately, I own, despite not having a PS2 (it came bundled with the PS2 copy of the game, a friend gave it to me). I also simply *had* to include Isolation in a thread where's such a bovine apocalypse enthusiast like you.
