Ten worst superhero TV shows
Going through the list, we start with Birds of Prey. The first mistake they made (and there was a myriad of them) was altering Batman's daughter to have superpowers. I guess the WB was trying to copy the success of Smallville into other superhero shows and failing.
I remember seeing one episode of Once A Hero. I'm only sorry they didn't air the episode in which Adam West parodied himself. I missed Exo Man altogether (but only in the sense that I didn't watch it).
KISS Meets the Phantom of the Park was filmed while KISS the band was in its declining years. Gene Simmons moved on to other things such as Family Jewels and Ugly Betty.
The Thor episode mentioned isn't actually Thor, but rather the TV movie The Incredible Hulk Returns. Marvel Comics was actually trying to launch television franchises of their other superheroes. Sadly, religious groups didn't like the portrayal of Thor as a god, so he was demoted to a "mighty warrior." And when they introduced Daredevil in The Trial of the Incredible Hulk, he wasn't allow to be red or have horns. I believe Marvel also wanted to introduce She-Hulk and Iron Man in two more Hulk TV movies, but nixed it and broadcast The Death of the Incredible Hulk instead.
I never saw My Secret Identity, but I dig seeing Jerry O'Connell from his time between Stand By Me and Sliders (and Carpoolers), before his big weight loss.
The Captain America TV movie was more trying to cash in on Evel Knievel's success (as well as The Six Million Dollar Man and other '70s icons) rather than make something true to the source material.
I remember Legends of the Superheroes quite vividly. It could also be called "Adam and Burt's last hurrah." Borscht Belt comedy meets the Super Friends. You could tell affirmative action was in play when the character of "Ghetto Man" was introduced. I only wish I was making this up.
Wonder Woman without Lynda Carter. Pass.
Finally, there was the Justice League CBS pilot from the '90s, which was trying to cash in on the new, more humorous Justice League incarnation in the comic books. While containing major suck, it did include appearances by John "Crypt Keeper" Kassir and Kim "Son of the Beach" Oja as well as David "Can't Stop The Signal" Krumholtz in a supporting role.
This list made me laugh. While it's not quality television, I recommend taking a look.
