Pick: Star Crash. (This one's for SBC.) The worst sci-fi movie I've ever seen. And that's saying quite a bit. Enemy spaceship shaped like a claw that makes a fist when under attack. Robot with a bad Southern drawl. Heroine (Stella Starr) who wishes she was Barbarella. David Hasselhoff as the prince of the universe. Soldiers fired in hollow torpedoes to board the enemy starship by crashing through the windows. And that's just off the top of my head. There's more idiocy in every minute of this than should be possible, even in an infinite universe.
And just because I'm amused, here's Episode 2 of "Angel of Death"
Say g'night, Stella.
