I love it.
I have seen all of Dargonball (except for the red and blue saga) and most of Dragonball Z (all the way upto the Majin Buu saga) and I have all of Dragonball GT except I havn't watched them yet. I also have all the movies of Dragonball Z and the Dragonball GT Movie. I also have a Dragoball Z Fan Character by the name of Vex (when fused with my other character Cosnett he becomes VexNet, hence my username also I have Vex in my signature picture aswell, He is the Saiyajin in White).
Cell saga was also one of my fav sagas too, When Gohan went SSJ2 and killed Cell <3
Gohan is my favorite character out of all the seasons, I wish I could take after and be more like him (even tho in my head I see myself most like him out of all the DB/Z/GT people). I also based Vex off of Gohan.
In my opinion it's one of the best animes out there still. Plus it makes one hell of a videogame, I love and have Dragonball Z Budokai 2 & 3, I also have Dragonball Z Goku's Story 2 for the GBA. I also plan on getting the new Dragonball Z fighting game for the PSP. If I get a Nintendo DS I will be importing Shonen Jump Star aswell because it has Goku and Naruto in it.
I also agree that it's so good to inspire other shows like Bleach and one of my other favorite shows Naruto.
Despite what a lot of people say about the show being too long and too boring with many fights lasting several episodes (or an entire saga) I must state that this is one of the shows strengths aswell, I was watching them and never got bored of seeing them battle it out, If you don't like it, turn over and don't complain. I read a review somewhere also stating that the long battles are good in a way that the reader/viewer feels some of the strain of the badguy not dying and you wanting to beat him a lot but your just simply not strong enough (a lot like an RPG game before a boss sometime, It strives you to try harder) and keeps you watching to know how it ends.
I know one scene that is kinda stuck in my head, During the Majin Buu saga (or maybe the fusion or just before it.. ) when Goku is trying to teach Goten and Chibi-Tunks how to fuse and he gets Piccolo to demonstrate it and he gets really embarrased, then when Goku leaves Piccolo tries get another to demonstrate it and everyone runs off XD I found that funny.
anything else to say?
I Love Dragonball Z!!!
