Toxic Avenger is the only one I've ever seen. I remember watching it on USA Up All Night, as soon as I saw it released on DVD I picked it up. What other Troma movies are definitely worth watching?[/QUOTE]
All the Toxie movies are pretty good. I have Tromeo & Juliet, but haven't seen it (it was only $3, so I bought it). I also liked Sgt. Kabukiman, NYPD.
EDIT: I know it's not really a Troma movie, but it is under their banner: Cannibal! The Musical.
