However there where also a 100 shows kind of like GI Joe and Transformers at same time that all died after a season or two and no one remembers. It would be interesting to see if anybody has done any analysis as to what made the successful bad show more successful than the unsuccessful bad show.
Compared to most of them, Pokemon was actually pretty decent. It had a (very basic, but still...) storyline about kids going off on kid adventures and meeting lots of weird cartoon animals. I mean, sure there was the whole "catch wild animals and train them to fight each other" thing but it wasn't really any more violent than the GI Joe or He-Man or Voltron shows I watched as a kid.
Going back to those, the only real common negative thread is how they were basically ads for toys and games. Taken outside of that, I saw Pokemon as a halfway decent "starter anime" that was loads better than some of the live-action cartoons of the time (Power Rangers and its knockoffs were just awful).
