That's been my opinion, too, but a lot of the people I've spoken to don't think they need it. And to be completely honest they don't because once the initial infatuation has died down, most of them don't take it much further. It is sigh-inducing, however, to hear an entire community insisting that I am wrong simply because their peers say so - their peers who, incidentally, have never studied Japanese either. Watching anime for 5 years does help some things but it does not make you immune to mistakes. Ah, well..
