I liked Inuyasha when it first came out, but being 14 at the time and just then discovering more mature Anime, I think that opinion of those episodes could easily change with my current experience. When the episodes got past about the 20 mark, I lost interest, as the series was obviously going downhill, from my recollection at least. Really, I think the main reason it stays on there is because of all the fanboys and fangirls who would have a stroke if it went off the air.
I never really got into to too much of Adult Swim's Anime showings, besides Cowboy Bebop, but I mean come on, Cowboy Bebop is amazing and a true example of what Anime is capable of. If anything, that series should always be aired, basically because of how significant it is, at least compared to Inuyasha. I was also into Yu Yu Hakusho for a while, but after the Spirit Tournament (or whatever it was) I kinda drifted away from that series.
I don't watch nearly as much Anime as I did since about two years ago (although I am part of my college's Anime club, which is pretty much watching and critiquing/celebrating anime of all forms). I find myself enjoying traditional American comics more so than Manga these days, too. I feel there is a lack of new material that impresses as much as Anime and Manga did a couple of years back. I watch Code Geass here and there, but it definitely isn't one of my favorites as much as it is one of the only new ones I can get into somewhat (although its hard to look past its similarities to V for Vendetta).
I can only hope more interesting endeavors come to light in the medium that is Anime, and soon.
