xxxHolic and .hack//roots surprisingly good, those two are my favorite new shows. As for older shows, Keroro Gunso and One Piece kept going pretty good, never lost interest in them. On the live action side, there's a J-Comedy called Gal Circle that I've been watching, pretty funny and it's got a good ending theme, and there's Stand Up, a J-Drama, Kamen Rider Kabuto, Sazer X and Boukenger. All of those are my favorites, a little more than usual actually.
As for least favorites...Soul Link was bland and boring and Nana was nowhere near as good as the manga, nor was it as good as we were told it was going to be.
