I don't particularly rate Anime any differently then I do western Drama Serials, Sci-Fi or Fantasy. Some is good, a lot is shit... it's case by case and entirely subjective.
The question been posed is similar to "Do you like or dislike this genre" but it's even grander then that as it's more culturally rooted then genres, which are socially rooted.
I have seen enough tripe in all mediums to safely say that none of them are "my kinda thing" but I will keep watching/reading/playing/listening in hopes that I catch the rare piece that does interest me... the rest is passing fancies, forgettable brain trash and nights in/out with friends/partners.
So do I like Anime... I suppose, but that's about as bad a generalisation as hating everything too.
EDIT: Just to try and clarify my point: I find it hard to believe that someone cannot at least like one of the following:
Ghost in the Shell, Akira, Spirited Away, Princess Mononoke, My Neighbour Totoro, Grave of the Fireflies, The Girl who leapt through time, Macross, Blood, Ninja Scroll, Cowboy Bebop, Bunny Drop, Panty Stocking and Garter-belt, Neon Genesis: Evangelion, Naruto, Bleach, One-piece, Dragon ball, Speed Grapher, Death-Note, Fullmetal Alchemist etc.
Unless they are totally opposed to animation or have an aversion to Japanese culture and film.
