GT is no joke. It's just a way to make a lot of money. I think they could've done a much better job, they would've gotten more money that way, too. I don't understand their logic.
DragonBallZ has suspense, GT just doesn't drag it out like it should.
There are a few good episodes, granted, but what the heck is up with Gohan and Goten almost being destroyed by Goku with only One kamah wave? I could understand Goten, but Gohan? He's suposed to be stronger than that! The strength and power system is all messed up.
That being said, I did enjoy Vegita being taken over by Baby. That was good. And the whole "Goku's stuck in a game of chance and can't use his powers" was original, and kind of funny.
So yeah, GT has it's redeeming qualities. Still, it could've been much, Much better.
