20th Anniversery Mystery Science Theater 3000 box set. Four enjoyably cheesy movies:

Werewolf: Like Skinwalkers, it exploits Navajo mythology for horror effect, but in this case winds up looking silly. One of the hammiest villains and most wooden of leading ladies.

Laserblast: Was that Mark Hamill? Unhappy teen stumbles upon an alien weapon and gets a chance at revenge on everyone who picked on him.

First Spaceship on Venus: Spiritual precurser to movies like Mission to Mars and Red Planet, but more pretentious. International crew fly in a rocket ship to Venus to look for signs of life with some of the goofiest equipment you've seen outside Looney Tunes.

Future War: Low budget rip off of the Terminator that throws in animatronic dinosaurs for good measure.
