and is/are they any good?
Personally the ones i'm watching as they're released are:
Hunter X Hunter (Greed island final ova)
Ghost in the Shell (2nd Gig)
Initial D (4th stage)
And series that are already finished and I'm watching them now
Hajime no Ippo
I'd recommend any of them, but the ones that I'm enjoying the most are Planetes, Hunter X Hunter and Naruto
