Back when I was 18 or so, I enjoyed Dbz for what it was, but I admit the drag of the series and lack of explanation of anything got way too much, what was interesting at the start with Goku's origins as a , Nammek and freezer just dragged on into an onrunning battle, then after that it just seemed sets of more and more random villains turning up. My interest waned after things got into the boo saga, sinse it seemed the series as a hole was just treading water at that point aand potentially interesting characters had been abandoned for just stalling, heck during the Cell saga I remember there was one episode which just featured Trunx powering up, and lets not even get into the "and this will happen in five minutes" business.
it's odd, sinse I liked the build up and atmosphere and the epic nature of the villains, then however I discovered ruroni kenshin, in particular Season 2 the saga of Kyoto which managed to have a lot of what I liked in dragon ball without any of the craziness or bad timing but with the fights you respected.
Gt my interest had pretty much taled off, particularly because all the promise in Dragon ball Z had just failed, for example we have huge amounts of time being told how tough gohan will be and how he's stronger than his father, then the first thing that happens in Gt goku gets reduced to childhood by some random craziness and Gohan gets forgotten about.
It's like the problems of Z on a grand scale.
I confess this is why I've never looked into either the original dragonball or Dbzk, although I've heard that many of the issues with dbz were sorted in the retelling with K, especially the long, long dragging plots and battles that went on forever. I wouldn't mind seeing it at some point, but it's not something I'm going to actively go out and buy or anything sinse there are far more things I'm interested in watching/reading/listening to.
Then again, sinse Dbz, I have found things that had that same epic quality that I really liked in dbz, but managed to do it without the nonsensical universe, stagnating plots or total lack of explanation. ruroni Kenshin for example, particularly in it's second season battle of Kyoto. Indeed at the time we watched it, my brother called it "the thinking man's dragonball" sinse it has several of the same ideas, distinct good and evil characters facing off in one on one battles that last several episodes with some other cast members who act as the audience, techniques (though sword techniques in the case of kenshin), with specific names and histories and counters and a very much good vs evil motief.
Yet,Kenshin manages to actually have a plot that matters and have more than one character who makes sense. Also the reason the battles, especially those with the jupon gatina go on for several episodes is that in the middle of the fight you will get the villain's life story and the way they are defeated usually reflects this. I also like in Kenshin the fact that all of the characters pretty much get their own battle and opponent, and though Kenshin as the titula hero of course has the battle against Shishio, the big enemy he still needs help with that one.
I also like Kenshin's personality and fighting style, given that he was a samurai assassin in the war that overthrew the shogunate, killed many people, however then grew totally sick of killing so fights with a reversed blade sword, with the sharp bit on the inside of the curve not the outside so that he won't have to take another life.
This is also what makes Shishio completely evil, sinse he's the person who took over from kenshin as assassin, but is a complete opposite, indeed his back story is that the government shot him and burnt his body to prevent him from revealing all the nasty deeds he'd done for them, so appears as a scarred wreck with dramatic bandages who is a complete psycho! quite different to the actually fairly small and usually quite clumsy Kenshin in his white and pink ronin outfit.
Of course there are other battle anime and other epic anime as well, but Kenshin was the one that struck me in tone as closest to Dragonball, even if not in setting, as well as being different from say things like bleache in not suffering some of the same problems Dragon ball did, at least for it's second series, ---- the third season did get a bit loopy, though it did also have some interesting villains as well.
With our dreaming and singing, Ceaseless and sorrowless we! The glory about us clinging Of the glorious futures we see,
Our souls with high music ringing; O men! It must ever be
That we dwell in our dreaming and singing, A little apart from ye. (Arthur O'Shaughnessy 1873.)
