In my opinion, there isn´t so much good anime movies, i prefer more series...
Mononoke Hime is quite awesome (i don´t like other movies from studio ghibli)
and there is few movies which are great, but you need first watch the series like:
Higurashi - Outbreak, Steins;gate - Fuka Ryouiki no Déjà vu, Hunter x Hunter
and Mushishi movie was really great !
I haven´t seen Sword of the Stranger, but that seems quite interesting, so rooting for it....
pictures resembles like Ninja Scroll.
here is a short list of animes which i really enjoyed and are about ~13 eps.
- Corpse Party - Tortured Souls (only 4eps, 30min each)
- Mononoke (the series, not hime)
- Tasogare Otome x Amnesia
- Nazo no Kanojo X
- Chaos;Head
- School Days
What kinda genres do you like or dislike?
there is quite much really, really good ecchi animes also like Highschool DxD or Sora no Otoshimono
but some ppl might get too irritated....
Higurashi, Steins;Gate, Shingeki no Kyojin, Claymore, Kore wa Zombie Desu Ka?, etc, etc, are fantastic, but maybe too long for this project.
and there is also some nice short series (about 4min each episode) like Ai Mai Mii, Senyuu and Nyanpire : D
it´s quite hard to try to pick up some series which everybody can enjoy. you really can´t argue about tastes.
