I'd say it's decent, not the best movie made by 'Disney' but far from the worst either. I remember that I really enjoyed watching it when I was a kid. Although, I must say that even then I liked the books it was (loosely) based on more.
Regarding the two lists, the only movie that would have a chance to get into my own top 5 would be 'The Iron Giant'. I haven't seen 'Waking Life' and while 'Land Before Time' was another one of my favorite childhood movies, nowadays, if I had to pick one movie made by Bluth I'd pick 'The Secret of NIMH'.
I'm also a bit surprised that none of Miyazaki's movies were mentioned.
On the bottom 5: Well, I've only seen snippets of 'Fantasia' and thus I can't really judge the movie but I liked what I've seen. Haven't seen 'Fritz the Cat' and I actually liked 'Yellow Submarine' (mostly because of The Blue Meanies) and used to watch it again and again until my tape broke.
Regarding 'Rugrats the Movie': I've never been a big fan of 'Rugrats' (it's mostly the character designs I don't like) so I'll agree with him on that one, out of pure bias (the sequel when they went to 'Paris' was pretty awful as well). As for 'The Lord of The Rings'; yes, it's bad but it did introduce me to the world of Tolkien and for that I'm grateful.
