GT is shit, I will give you that, as is the Buu Saga, but the anime isn't that bad, and the american VA are way better then the japanese one after the starting with the saiyan arc, and the voices used in dragonball are overall better then the japanese VA. Its not the greatest anime, for sure, there are better shonen jump one out there, like YYH. And the american cast is also way better then the spanish or, gosh forbid the Portugal VAs.
I dont understand your stance on the movie though. They're very neat 'what if' stories, with no ties to the sagas that I think has done better job at highlighting characters strength then the show does. My favorite movie is the tree of might, and the dead zone... the name escapes me of the movie that takes place in the afterlife with a lot of candy... That one shows Vegeta tactical thinking fairly well, something that more often stated then shown in the series. Most of them are okay.
I also don't understand your complaint of voice actor doing more then one role, thats fairly common in both american voice acting and japanese. Its economical and practical.
The editing, and localization arent that great, yea. The cartoon network DBZ mostly uncensored reshowing does a better job in my opinion with that.
I've read Akira once, a very fine read that everyone should read through once really. I havent heard of the eden one though. Whats it about?
I was reading this one magna, that was in the near future, about debris cleaning of earth orbit. One of the main characters started to do the work, as a debris cloud killed his wife, and during the first book he found his wife ring while cleaning deris. I cannot remember the name of it, its drive me bonkers.
