The Violent Kind......stoooopid.
2 different movies intentionally taped together....
Probably more of a "Let's make the most unexpected plot twist EVER!!!!" than an actual splicing of 2 unrelated movies, but a failure nonetheless...(but maybe worth watching once....if you have nothing else to do)
SPOILER
Starts out as a a young hell's angels party and have fun with some organized crime plans and a few love interest/ actual plot moments, when suddenly it becomes a little too "EVIL DEAD" all of a sudden.
That gradually morphs into Omen/1950's greaser aliens killing all humans. You know, the usual.
If plot twists that EXTREME made for entertainment, then we would just make movies that are 1/2 terms of endearment, 1/2 Mickey's christmas special.
