2) You can't turn into an Oozaru if you're watching the Earth, the Moon has special waves which are transforming Saiyajins in Oozaru. If Moon = Earth then Radditz, Nappa and Vegeta would have died when they arrived on earth because they would have turned into Oozaru in their spaceships.
3) The staff forgot the ultimate state, Gohan was, is and always will be in his ultimate form. His ultimate form IS his base form since the end of the Buu saga. All of his powers were unlocked, he's always at his max, he could most likely turned into a SSJ again but he wouldn't be stronger, only his look would change but his power remain the exact same and on top of that it'll affect his life time. So it can make him weaker but there shouldn't be any reason for him to use SSJ because like I said he's suppose to be at his max already and all of his strenght is unlocked so even with a SSJ4 or 7 or 8 his power should be the exact same. And in GT nobody (old Kai, Gohan himself or whatever) is referring to this form again, nothing is explained and nobody is surprised... It's like "nothing happened".
4) The lack of SSj2 doesn't make sense, even for Goten and Trunks. They're clearly able to turn into SSJ like nothing and they mastered the SSJ3 in fusion (a fusion that GT forgot...again) and they can't use the SSJ2 20 years later? Ok...It seems the others forgot about that form too anyways.
5) Villains don't keep their bodies in hell, it's stated by Piccolo when Vegeta was against Fat Buu so Dr.Gero and Myu can't drink wine in hell, can't create a second android 17, can't bring villains on earth, can't connect two androids 17 and they can't keep their memories in hell.
This whole saga doesn't make sense.
And on top of that we can see Coola when the villains are coming back next to android 19 (which can't be here according to the book 'cause dolls have no soul).
6) Another thing, Shenron can't turn Goku into a kid again. He can't because Goku is stronger than he is, Shenron couldn't kill the Z-warriors ennemies or make changes on android 18's body for the exact same reason.
7) And in SSJ4 Goku's adult for no particular reason except for the look but other than that there is no explanation whatsoever.
8) The power levels don't make sense at all. It's creating inconsistencies everywhere. Goku losing to a regular child at the Tenkaichi Budokai doesn't make sense and was the most frustrating scene I ever witnessed. GT has inconsistencies and plotholes, and there are too many choices which are wrong and even when they're trying it's not funny, it was only done for marchandising and for money.
9) Plotholes and inconsistencies aside many are out of their characters, Tien and Yamcha at the very end when the Dragon Balls weren't here anymore did not help the people, Tien was taking a shower and Yamcha was reparing his bike (from the end of episode 64). Even if they are useless in the context it's pretty hard to argue or to prove that at such time they wouldn't show up at least to help the GT-warriors (give their strenght) or the regular peoples who were threatened by the fight against Li Shenron. Even in the Baby saga they didn't do a damn thing, even if it's hopeless Tien's character would help in vain (Buu saga for exemple, Fukkatsu no F) same goes for Krillin, Yamcha AND Piccolo.
10) Gohan one shoted Piccolo but come on, Piccolo unlike Gohan is still training and it doesn't take weeks for someone like Piccolo to regenerate himself and to help the non-Baby elements (what was he doing the whole time?).
That's the problems I had with GT, then Dragon Ball Super came out and did a worst job in many aspects. Now I look at GT and I'm like, was it really "that bad?". Maybe but the animation was outstanding, the musics were "ok" and many fights were entertaining, the series had a different approach and moral than the earlier works and manages to deliver it through an impactful and emotional ending. Its conclusion was probably better than the original one and despite its flaws it brought something new to the series.
