Brain Powered has good music (go Yoko Kanno), so there's that, at least. Its opening credits, which feature (from what I can tell) the entire female cast naked are weeeeird. It's not a show you would get the impression from watching an episode of here or there that there was any nudity at all, so it's rather jarring.
X the movie is certainly down there.
Kenshin, Bleach, Naruto, Inu Yasha...I can't say I think any of these are all that bad. Not necessarily worth watching much of, but they all have their moments. Inu Yasha, in particular, I think is really good until it gets too repetitive, and even then there's good cast interaction to keep it afloat. Naruto's anime is rather badly-paced, but it has flashes of greatness. Kenshin...ok, I can't think of anything good to say about Kenshin.
