Hm, seems i yet have to find a good parody of anime exceot for DBZ and Yugioh.
Tbh, i do think that it is not possible to like a parody of an anime you really like as in LOVE and take serious.
I mean, i like dragonballz and dbza, but only because i dont see dbz as serious, and the addition of trash humor just makes it funnier.
For example, a hunter x hunter abridged deconstructs memories of serious and emotional scenes i grew fond of, and i dont like that.
A good one piece abridged is hardly possible, too, because one piece does so much fun of itself that it is hard to make s th good out of the leftovers.
The yugioh abridged works great because there is just so much to laugh about regarding yugioh, whether it is the horrible plotline, the incredibly shallow characters or the even more absurd spin offs.
Also, i do think that it is best to abridge s th that is outdated, because it is like a revival for people who watched it back then as kids or young teens.
I for example was a die hard dragonball fan as a kid, as a teen i found it stupid in retrospect and hated it, and now i love it again due to dragon ball abridged.
same goes for yugioh.
Hunter x Hunter is an ongoing series (well....sometimes), thus people are still too excited about the actual manga and anime.
