The movies aren't that bad, except for Bio-Broly, Broly: The Second Coming, and Path To Power (... for a Summarization of Dragon Ball, it sure got a hell of a lot of stuff wrong.)
The fights were only so long (ex: Frieza Vs. Goku over 10 eps of fighting) because they were forced to convert 12-14 pages of content, into 19-23 minutes of footage, plus the Anime was running right alongside the Manga releases..Originally Posted by Darkprinny
Any other Anime that was transitioned from Manga to Anime (under the same circumstances as Dragon Ball Z), would experience the same treatment of expansion (extra talking, extra unnecessary movement). So I wouldn't really count that as a negative towards the show, since there was nothing they could do about it. Which also explains the excess of flashbacks, and the excessive amount of dialog.
