I’ve never been able to really get in to MST3K, despite being fond of the concept. It feels too gimmicky with the space theme and the robots, but I don’t think I’ve really given it a chance. There are a lot of episodes and different eras of the show, so I don’t know where to start. Are there any great episodes that are worth trying?
Red Zone Cuba - black and white film from 1966 depicting the Bay of Pigs as being carried out by five guys. Very slow and boring film, but hilarious to me, an underrated classic. Great bad theme tune to the film too ("Night Train to Mundo Fine").
The Incredible Melting Man - 1977 horror film about an astronaut exposed to radiation who then begins to melt and kill people.
It Conquered the World - black and white 50's sci-fi directed by Roger Corman. A cult classic film and entertaining in it's own right, with one of the all-time greatest bad movie monsters, which I won't spoil by describing. I mainly love this episode for the very serious monologue delivered by Peter Graves in the last few minutes, and the way that MST3K makes fun of it after the film has ended (and into the end credits of the episode).
Blood Waters of Dr. Z - Also known as Zaat, just a weird, grimey 70's film about a scientist who turns himself into a monster because of his desire to be a fish.
It's honestly really, really hard to pick out episodes to start someone off as each episode can be so different depending on the film they've got to work with, and a lot of enjoyment could depend on what type of film you prefer. Each season is also very different in its humour.
