Spectacular Spider-Man. I swear this was the only show I would sit around waiting for the next episode to happen. When people were seeing season 2 in Canada, I was foaming at the mouth waiting for it to be shown online (as Disney XD didn't only wait forever to show it, but it started at season one when it did [which was pretty much after all of the episodes from season 2 were aired in Canada). The worse part of it all...they were just getting started with the really good stuff. Things like Jameson having enough of a reason to hate Spidey and to finance the Spider Slayers and the Scorpion and Roderick Kingsley's rise in the world of crime as the Hobgoblin were things that were already set up. Just watching the show gets me irritated on what could have been...Oh and it was the show that got me interested in Spidey in the first place.
Wolverine and the X-men. Another show that I thuroughly enjoyed. Although the title character's episodes were pretty lackluster, any episodes focusing on other characters were GREAT. Someone needs an award for episodes like "Fallen Angel". Also, like Spectacular Spider-Man, the show was really starting to get to the really good stuff with the Age of Apocalypse. Thank goodness they got the Pheonix storyline out of the way.
Filmore!. I loved this show when I was younger. Then again, I was in high school when it was airing and could understand the parallels to the Safety Patrol and the police...and I loved it!
The Critic. I loved this one as well, as it was pretty clever with the humor. The movie parodies were great and such a fun cast of characters. How this show went off the air with the Simpsons STILL on today baffles me...
