I've read the manga for Inuyasha its not that appealing. DBZ is godawful.

For the good ones, Neon Genesis Evangelion is certainly a must, I'm quite fond of Rurouni Kenshin myself (Samurai X being the OAV). I've heard good things about Hellsing and Cowboy Bebop, and many people like Trigun though I've heard of people who dislike it. As I said earlier, there are many good anime, and there are many bad anime, its no different than any other form of cinema. You wouldn't make a broad statement such as "I hate movies" right? This is essentially the same thing, anime is far too broad to be classified as one entity.
