Well I'm just going to mention what I've been WATCHING in 2010, which is not the latest..

this year I rewatched Dragon Ball Z (HELL YEAH!! best thing ever.. gohan SSY2! :O:O)
then I watched for the first time YuYu Hakusho (that show was the balls!!)
now I'm currently watching Bleach, bleach is sick but sometimes it can be really boring...
Moreover I started learning Japanese, so I have begun watching it in raw jap form and i understood so little. hehe ^_^
but yeah these shows all rock...

somewhere in there i watched full metal alchemist, might have been last year though.. now that was really cool and original, but i don't feel the critical acclaim my friends have for it.
