Final Sacrifice & Space Mutiny are at the top of my list, but I've rewatched them so many times I can just about recite them line for line from memory. Same with Mitchell & Sidehackers.

I've started more carefully watching episodes that I may have originally written off as boring or too awful to bear & I keep discovering new hilarious riffs that I missed on the first or second watch. So I'm discovering new favorites as I go. e.g. I watched Lost Continent earlier today & was in tears.

Resurrecting this thread to add my take- My favorite episode overall would be The Day the Earth Froze, but Here Comes the Circus is a big part of that. If I were to take the movies alone, my favorite would be Overdrawn at the Memory Bank.

If we restrict it just to Season 13 (for funsies), it would definitely be Beyond Atlantis.

I think I’d have to go with Riding With Death. So many great 70s jokes, and I have some great memories of my dad and I watching it together. It’s practically the perfect MST3K episode, just straight comfort food for me.

My favourite is probably Time Chasers, partly because it's a great episode in its own right, but also because it was the very first episode I saw, and I don't think many things have ever made me laugh as hard as I did that day.

For Castleton!
