There have been spectacular animated movies from all around the world. Heck, i've probably seen 5 times more than you ever did, and I do not consider myself know enough in the genre.
I do not know much about musical movies, and just because i've enjoyed some of them, it wouldn't make me appropriate to go and post a poll about it.
Next time you do it, at least see and put in the polls pionner movies from France like Le roi et l'oiseau (The King and the Mockingbird), recent classic like Kiriku and Les triplettes de belleville, to older Asterix movies like the great Asterix chez les bretons (asterix in Britain) to some of the biggest pionners in the animated field: the asian for godsake!
Where's the first feature both Miyazaki and Takahata did that changed the face of animation ? (Horus Le prince du soleil, or Little Norse Prince here) Where's all of the Osamu "God and creator of anime" Tezuka adapted films ? Where's the filmmography of both Hayao Miyazaki and Isao Takahata, from Totoro to Goshu the cellist ? Where's Mamoru Oshii's list of controversial and modern classics films ? (From Angel's egg to Ghost in the shell). Where's Otomo's pivotal Akira ???
Jesus... I might sound harsh, but what I just listed are FRAGMENTS of what he should have put in there. FRAGMENTS!
Heck, I love american animation (from the Fleisher brothers' old superman cartoon, to looney tunes, to the iron giant, to disney's huge library to even recent brilliant show like the simpsons, samurai jack and Avatar) but they are far from being the only one out there.
Heck, even The last unicorn and flight of the dragon are missing. Where's most of Ralph Bakshi's movies like the great Fire and ice or his most well know failure Lord of the rings ? Redo the whole thing when you've seen or AT LEAST know all of the movies i've mentionned, and then go deeper, and comeback and rewrite a poll.
Edit: to clarify things, this is a post to suggest seeing these animated classics. If you feel lost reading these titles, than go seeking them. They are great. If you feel insult, than i'm sorry, that wasn't the goal here. This edit is to clarify a reply I got after that.
