Tromeo and Juliet
Got to love them all
Don't forget about Terror Firmer. It's like the "Scream" of Troma movies. One of the finest imo. Lots of great names were in/ associated with the production. Joe Lynch, Eli Roth, Trey Parker, Matt Stone, as well as Will Keenan, and Trent Haaga.
Aside from the ones you guys previously mentioned, I'd say these are worth at least a one time watch, as well.
Mother's Day (original) the remake is arguably better, but like comparing apples to oranges.
Terror Firmer has to be my favorite Troma film. It's a riot.
