You find b-movie fans everywhere!
I really enjoyed Little Shop, though I saw it on one of those huge public domain DVD collections (you know those?) so the quality was bad. I'm pretty sure that added to the charm, though.
Yep, those collections are fun. I watch most of mine on the late night blocks with the running commentary (you know the type

).
I'm actually planning on watching Toxic Avenger soon, as I've never seen a Troma movie.
Man, you don't know what you're missing. Their films are classics. Just need to remember that their films aren't serious. Also, expect to see some cast members you wouldn't expect

Last time I checked, which was about 8 months ago, you could watch quite a few of their films on Hulu.
