Invader Zim was a favorite of mine that disappeared far too soon, and Enter the Florpus is all the chaotic B-movie mayhem that you would hope. It regularly jokes about how the show has been gone for so long, but it proceeds from there into another classic ZIM adventure.
The art is still fantastic, perhaps even improved. The voice cast has returned and are at the top of their game.
I hope this is a sign of more to come!
