As probably every top list of smth, it mostly tells us about certain experience of the author or authors of the list in the medium rather any good representation of that medium, though I doubt any list is capable of presenting such wide diversity of animated movies as it's today.
Overall, outside of Fantastic Mr. Fox, which was a pleasant surprise, nothing is out of the ordinary. Authors are clearly tend to admire or simply have limited knowledge outside of popular Disney movies (even massive heritage of Disney could be presented better) with a little bit Pixar here and there (the studio worth mentioning only because of Toy Story, but nothing more in my opinion) and anime (while japanese animation is not limited by anime, but including Ghibli movies is nice for diversity, since their works are arguably outside of the anime genre to some extent). On top of that, authors seem to ignore a lot of animated movies of the past, instead they laid to much stress on relatively recent movies, alongside with truly great works they've included in the list a lot of derivative and forgettable ones. This's either due to authors being young or lack of knowledge of history of the medium, and as result underestimation of influence on the medium of some old movies.
//On sidenote, it'd be great if people will recognise some other traditions of animation that vastly differ from what's been presented in the list. Such as old European animation (including East-European animation of Czech Republic and Poland), animation of Soviet Union, Chinese animation, Indian animation, Japanese animation besides anime, Azerbaijan and Iranian animation, modern independent animation etc. Those are obvious underdogs, but a lot of great works.
