-Karin
It was amusing, though wasn’t really in my list of personal favorites. Worth a watch at least.
-Vampire Hunter D
Both the first and second movie were interesting. I actually liked the second more, but that may be due to the fact it was so long ago when I watched the first and it wasn’t as fresh in my mind.
-Jigoku Shoujo
I got bored with this one fast… It was pretty much the same thing every episode with different characters and a slightly altered plot.
-Death Note
Very, very, worth watching. It’s on my list of favorites.
-Tsukihime
Although a lot of people trash on this anime in comparison with the game, I actually enjoyed it. The reason for this is because I looked at it as a different story telling, rather then an exact replica of the game. The game was better overall, but the anime is still worth watching if you’re a full blown fan.
-Sola
It’s hard to say with this one… So much could have been done with it, yet the ending left a -lot- to be desired. Still worth viewing though.
-D Grayman
I love this one.(When it’s not filler anyways.) When it isn’t on filler, it’s amusing and the cliff hangers for the next episode are very brutal. Very worth watching.
-Zero no Tsukaima
Pretty much a one time viewing affair for the laughs, but that’s pretty limited.
-Xenosaga
Considering I’ve only watched one or two episodes because I didn’t want to spoil myself for the game, I can’t really comment… Then again… I have all three games, and I’m still in the middle of the second one and can’t seem to get motivated to finish it.
You might try Rental Magica. If you like occult and so forth it’s worth watching.
Sunabouzu was fun as well.
