So after rewatching all of Dragon Ball and DBZ again, I decided\to give GT a chance and finally watch it, and sweet Kami was it boring. I'm not going to comment on the whole series since I just started, but I was so bored, and so frustrated at what was going on that I tried my best to just skim a few episodes of the Black Star Dragon Ball Saga and ended up skipping nearly the entire season up until the trio find out about Baby. My comments so far:
1) I'm not sure if this is popular opinion or not, but I actually like the idea of Goku being turned back into a child. Mostly because it reminds me that despite all of his strength and everything that happened in DBZ, Goku is still that same little boy he was in the Emperor Pilaf Saga (though a little less ignorant). My one complaint about this aspect of GT so far is that it seems as if Goku is merely there to be the muscle and only speaks when spoken to. Which leads me into this next point
2) Who made Pan the main character of this series? I know a lot of fans didn't like that Toriyama kept Goku's character going when Gohan was originally supposed to take his place as the protagonist of the series, but that's what he is. Goku is who the series is supposed to revolve around. And although the Dragon Ball franchise is an ensemble cast, GT really locked itself in the corner with these three characters in the beginning.
3) Not only is Pan made out to be the leader, she is extremely irritating. I know that's popular opinion and probably redundant, but she is just plain annoying and not in a funny, original way like Bulma was, she's just...blech.
4) In my personal opinion, Pan would have been a much better character if she wasn't such a brat. Her main character plotline should have been her attempts at emulating Goku and his accomplishments. (Once again, in my opinon).
5) I like that they matured Trunks from the irritating piece of work he was in the last few sagas of DBZ. Though of course he was (understandably) not close to being "Future" Trunks, he wasn't nearly as pig-headed as he was when he was a child. One example that comes to mind is when he refused to let Pan destroy Giru because "he values his life," and all that other jazz.
