Bad movies? I LOVE BAD MOVIES!
Especially old ones, and old sci-fi. I still have an extensive VHS collection and some laserdiscs of films that never made it to DVD, such as:
Slipstream (1989,Japanese widescreen laserdisc)
Deep Red (1994,laserdisc)
Out on a Limb (1992,laserdisc)
Hamburger: The Motion Picture (1986,laserdisc)
Dream Machine (1991,laserdisc)
Off and Running (1991,VHS)
Crazy Legs aka Off The Mark (1987,VHS)
Savior of the Earth (1983,VHS) - Tron ripoff cartoon you just gotta see, even if you only watch the first few minutes: https://www.youtube.com/watch?v=4OePa32O9l0
The Dirt Bike Kid (1985,laserdisc)
