Are there any really good fanimes out there?

I'm not really sure what you mean by high quality. ^^; Honestly, unless it's made by a group of people, high quilty finished fanimes may take forever to get done. And plus, majority of fanimes are made by one individual person. Either they had to cut corners with quality or they usually take a very long while.

Granted, there are some exceptions to that rule, like Magical Girl School is reaching to a close (as Emily Loves Cookies stated.) and Magical Nyoto Chan is kinda a half exception because that mainly started out as a troll fanime but it became less of that when episode four came about.

Though then again, both of those examples had been around for quite a while. Magical Girl School first came about in 2014 and Nyoto had been since 2012 (Though granted, it did had a 1 year and a half hiatus.)

Heck, even some fanimes that usually don't reach up to high quality levels usually take a while to finish, unless it's like a weekly challenge, like the one Evan started last year.

Super awesome dearthair crossover is finished, and I really enjoyed it.
