Funny that, I just started a collection of entertainingly bad movies. We’re at 100+ already. Highlights thus far include

Zardoz - Sci-fi Sean Connery in a future diaper.
Magic Magic - Horror movie Michael Cera.
Troll 2 - A Troll movie entirely bereft of trolls.
Showgirls - Stripper Nicholas Cage as played by Jesse from Saved by the Bell.
Critters 3 - Leonardo DiCaprio’s film debut.
Breakin’, Breakin’ 2: Electric Boogaloo, AND Rappin’ - no explanation needed.
