Hmm, well, i have no order to animes that i like but the ones i still gladly rewatch sometimes are:
* Gintama (All time epic)
* Romeo X Juliet (Just a Romeo and Juliet story in a fantasy setting)
* Lovely Complex (Frustrating fun)
* Hellsing OVA (Kicks ass)
* Soul Eater (Funny as hell, but i want an OVA)
* Onegai Teacher (Frustrating fun, again)
* Chrno Crusade (One of the best ever)
* Yu Yu Hakusho (Screw DB)
* Golden Boy (Pity they dropped it after 6 episodes, epicness)
* Berserk (I demand that they make the rest of the story, if not, i`ll do nothing! And i don`t care weather they read my post, damn it!)
So that`s it. Well, i actually have a lot of others, like Elfen Lied, that i want them to make an OVA of, Death Note until episode 24, and some other, ah well.
