I was very disappointed with Dragonball GT. Aside from the terrible animation, I was not at all happy with what they did with the characters. They shoved aside all the characters, all the important and main characters from DBZ and put the focus on only Goku and Pan. Sure, Trunks was given a bit of focus in the first season, seeing as he was the one who traveled with Pan and Goku to search for the black star dragon balls, but after that season? Nope.
I dislike many things about GT, like how Uub was supposed to be the new guardian, the new top fighter, as said in DBZ, but in GT, it was back to Goku again. I dislike what they did to all the main characters.
GT just wasn't enjoyable to me.
