The Lost Skeleton of Cadavera
"This was the day the Earth was disemboweled in terror"
This is probably the most well known movie on my list. I'll admit that when I first tried to watch this movie I was fairly drunk, and I ended up staring at the TV for 20 minutes. I don't think I blinked and I'm pretty sure I started to drool before I turned it off.
I had to go back and start this movie again semi sober before I realized what I was watching. Apparently director Larry Blamire has watched every episode of MST3K several thousand times and carefully constructed the algorithm for this movie:
1.) Remove all parts that are actually hilarious and meant to be that way (if any)
2.) Remove all parts that are unintentionally hilarious
3.) Remove all parts that are so bad, they're not even so bad they're hilarious
What we're left with is bizarre; an entire movie based on parts of bad movies that we nervously laugh at because we're not sure if they're so bad that they're funny or if they're so incredibly bad that they've killed multiple brain cells and made us mildly retarded enough to think that they are.
This is also the only movie on the list that is available R1, so you get a trailer link instead of the full experience. Netflix that shit!
