Do you know of any TV shows that had a good idea, but just didn't live up to your expectation?
The idea for American Dragon: Jake Long was great, but I don't really care for direction it took. I dunno, I was expecting something different. Not even the presence of mythical creatures and the concept of people being able to turn into dragons could turn me on.
Now if I were to make a cartoon about a person being able to morph into a dragon, I would've placed the setting in medeival times. The main character would be on the run from knights, and his/her best friends would be a fairy and a forest elf, who would travel with him. Oh, and it'd be drawn out anime.
