I think the show is amazing, but some episodes are definitely better than others. I remember liking Reptilicus. The only thing I don't care for are the skits, but I love when they're making fun of the films. It also looks like you're watching the new series, which I like from what I saw, but you may want to try some of the original episodes.
My favorite episodes are:
Mitchell
Hamlet
The Girl in the Gold Boots
Eegah!
Moon Zero Two
I Accuse My Parents
The Brain that Wouldn't Die
The Leech Woman
Merlin's Shop of Mystical Wonders
