Tales from the Darkside
Tales from the Darkside (1983) I feel is one of the perfect examples of something being so bad that it's good. The cheese factor is there, the forced 80s soap opera music is there. It's like Tales from the Crypt but without all the obligatory swearing and nudity that came with the fact that it was on HBO.
There are a lot of episodes where they felt like they had written themselves into a corner and the episode just ends abruptly without any real closure, but that just adds to the charm for me. They almost feel like stories a little child would tell without much forethought.
