1) Thundarr The Barbarian (obviously)
2) A Nightmare On Elm Street: Freddy's Nightmares
3) Conan The Adventurer: The Animated Series
4) WWE Saturday Night's Main Event
5) Manimal
6) Kung Fu: The Legend Continues
That's about all I can think of at the moment. Here are my reasons for each.
1) Thundarr was such an awsome show, way ahead of its time. I love my bootlegs, but unfortunately the sound and the picture's a little off on some of the episodes. It would be awsome to see them with digitally remastered picture and sound. And adding some special features, like episode long commentary for select episodes and some featurettes and fan films like what was done with the Dungeons & Dragons Series Box Set would be so awsome.
2) Freddy's Nightmares was released on VHS in the early '90s, so I don't see why they can't release it on DVD as well. At least release a "Best Of" box set with all the episodes which featured Freddy in the main story. Those were the only episodes I liked anyway.
3) Conan The Adventurer is available on VHS, so why not DVD?
4) I can't believe Vince McMahon hasn't done this yet. A Saturday Night's Main Event Anthology. He has a "Best Of" DVD, but I'd love to see all of the episodes in their entirety. So many great memories, so many classic moments in wrestling history. I've got several episodes of SNME on tape, but I didn't start taping them until October '86. And I didn't always get them all. I'd love to have all the SNMEs that I missed.
5) I almost forgot about Manimal until I read it on this thread. I thought it was a really cool show, and sadly under rated. It's a little obscure which is probably why it hasn't been released yet, but I've seen other equally obscure movies and TV shows availale on DVD, so you never know.
6) The original Kung Fu is available on DVD, as is Kung Fu: The Movie. So why not The Legend Continues?
