yes. i like cgi movies. i hope actors are some day obsolete. but in all seriousness, cgi allows us to do things we can't otherwise. that's why we have anime. and not all cgi (or even animation or "cartoons") are for children. but it's another art form.
i wouldn't say that "akira," for example, is for an 8-yr old.
but i wouldn't mind seing movies about mopeds. ;-)
