Im rewatching the entire series right now (American version with bruce falcouner music ftw!) and really here's where DBZ shines
+ Balls to the wall action, that is not only very cool looking but very fun at the same time. Also, for as long as the battles last, they are always fun to watch
+ The characters are incredibly charming and fun to watch. , even if toriyama seemingly forgets about Tien and Yamcha, you get cool characters like Vegeta, and future trunks
+Bruce Falcouner soundtrack and the dub are both incredible. It's one of the few animes that does the sound much much better then the japanese version does
+It's lighthearted and never really takes itself super seriously. All the character are silly, a lot of the events are unlikely, and many things going on in the show make no sense, but it's enjoyable
+It has the same effect Gurren Laqgann has, with it's "Holy shit how can they get stronger," and then the next episode you say the same thing
-Not only are the villains heavily flawed, but also the heroes, we don't get to see mary sue bull shit
Now for the negatives
-Forgets a ton of it's roots, and where it came from
-The universe set up by Dragonball isn't really expanded at all
- AAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA
-Super Saiyan 3 makes no fucking sense, and the different level of super saiiyans make no sense. The original Super Saiyan makes evolutionary sense as it allows you to be as powerful as if you were in your ape form, and be able to control yourself, something the saiyans kind of needed. Super Saiyan 2 (shouldn't be called that) makes sense for Gohan because he had that hidden talent all his life, and should've been the only saiyan to do it because he's a once in a lifetime fighter. Vegeta and goku going super saiyan 2 makes literally no sense as they really were just good fighters, not something special. And super saiyan 3 was stupid
-HOW DOES DR GERO MAKE ANDROIDS THAT ARE STRONGER THEN FRIEZA. Cell makes sense, he's made up of the best fighters in the universe, Androids were fucking stupid and im glad the villain changed when it did
- Garlic Jr Saga was one of the worst fillers ive ever seen in my entire life.
- Buu saga was awful
- Humans became useless, and so did piccolo essentially
- Trunks and Goten becoming super saiyans was so fucking stupid, don't even get me going on that
- Gohan got completely ruined by the Buu Saga
- Problems with contunuity
The way I see it is that Dragonball z is kind of like star wars, at first you had a guy who created a universe that was incredibly appealing to a large mass, and it was super succesful, but by the end of both persons foray, you could tell the main guy behind itt was getting sick of the universe and just wanted a cheap cash in. I would love to see a very talented writer start writing things in the dragonball universe, because it really is an incredibly charming universe, and that's what keeps us going back to it all these yearslater
