I miss MST3K to this very day! I wish some cable channel would start reshowing them from the very beginning (I think I missed the first 3 seasons).
The first two seasons weren't very good (it was unscripted). I've got every episode that's currently available, a couple were lost forever, from the original KTMA days to the last one in season 10.
However, you don't have to worry, you can just go watch Rifftrax
with Mike, Kevin and Bill, or Cinematic Titanic
with Joel, Trace, Frank, Josh and Mary Jo.
MST3K might be off the air, but the same people are still doing the same thing.
