3x21 Al Sah-Him
He's good! He's bad! He's dead! He's not! He is! He isn't! This season has gone round in circles far too many times. At least we're nearly at the end. I hope next year is better plotted-out, though.

2x17 The Mask of Matches Malone!
2x23 The Knights of Tomorrow!
The next two episodes flagged as the best by my survey. I enjoyed the first (an episode so risqué it wasn't actually aired in the US), and while the second wasn't bad I didn't love it as much as some seem to (note the very high score on at TV.com).
