Green Lantern: I agree with everything you said here except I really liked the Mogo story. Otherwise you are right about everything including why an anthology worked for GL and not Batman.

Superman/Shazam: I would like a Captain Marvel cartoon show too.

The Jim Henson Hour: Stick with Netflix or Blockbuster because I'm pretty sure this is out of print and mega expensive (it was a near miracle I found this for 32 dollars).
