To give some context, I watched Gurren Lagann last year. About halfway through the show
Digimon Adventure and 02 both had final battles that lasted 2 episodes. Tamers was a bit different, but the D-Reaper was a totally different kind of enemy, and was handled very differently than the general "fight bad guy" formula.
I honestly don't remember how long the final fight with Naraku was, but considering Inuyasha: The Final Act's insanely fast pacing, I'm sure it wasn't over an episode or two.
Finally, the big climactic fight with Shishio in Rurouni Kenshin, which I would consider its equivalent to the first Vegeta fight, last either 3 or 4 episodes. I forget.
Now, getting to the point, you could take all of these fights, add them together, and double the length, and they would still be shorter than the fight against Freeza.
Even discounting "5 minutes," fights in Dragon Ball, in my opinion, simply take too long. Watching a nicely animated chunk of Goku fighting Freeza is great. Watching some character-developing banter between Goku and Vegeta is awesome. Watching it go on and on and on and suffering due to obvious padding is not.
"Dragon Ball is known for its fights." I see this posted on here all the time. Yet, oftimes when you ask someone what was memorable about the fights, the reply is "they just stood around looking all constipated and yelling at each other for 10 episodes." I have friends who, when rewatching the series, tend to skip forward through the highlights of the Freeza fight, since most of it is pointless filler (this includes the fight in the manga. Half of that fight has no reason to be there other than senselessly padding out the story.) As much as I like the humor and zaniness of the Buu Arc, the majority of the fights consist of "stomp in one party's favor until plot happens and then stomp in the other guy's favor" with Goku vs Majin Vegeta and Gotenks vs Buu being the only real exceptions. And the less said about the fight against Perfect Cell, the better.
One of the big criticisms I hear about Super (and the only one I want to focus on in this thread) is that the fights in the tournament have been too short. Why is this a problem? From what I can tell, they're only "too short" in comparison to Dragon Ball, which already massively bloated its fights. At least from what I've been led to understand, Super's fights really aren't that much shorter than plenty of other anime I've seen.
I keep bringing up the Freeza fight because it is the most egregious offender, but it's hardly the only one. Kai did a decent job of managing this, but it could only edit Toriyama's self-padding to a limited extent.
So, this leads to the question in the title. Why do people like these long, overly-padded fights?
