For Day 7 we have The Incredible Melting Man!
How bad is it? 3.7/10 on IMDB
Why is it so bad? The monster is an astronaut who got “just a little bit radioactive” on a trip to Saturn, which somehow caused him to slowly melt. His reaction to this is to become a murderous cannibal that goops all over the place. This movies was originally intended to be a parody of sci-fi B-movies, but halfway through they decided to try to make it into an actual horror movie. Which is why it’s full of wooden acting (or overacting), cheap special effects, weird sound effects, silly scenes (such as watching an old couple steal lemons), and boring scenes (like a woman sitting alone knitting). On the bright side, a lot of people end up dead!
