The list.

Spirits Within came in at number 25, joining a rather illustrious group of animated films.

Now on DVD where its technical (much less creative) accomplishments can be fully appreciated, this film offers an intelligent, humanistic alternative to the conventional body-count approaches of live-action adaptations. -TG
While I can't say that I respect this list, or that I find much rationality in their ranking of films, I will say that I think their choice to include Spirits Within was a brave and interesting decision.
