It's probably more fun watching clips of the old show, indulging your nostalgia itch without diving in headfirst.

As for the comic, it's called Batman 66, it is current, and it's sort of... I don't know how to describe it, but it's like a remake of the 60s show.  I skimmed through an issue and it was interesting, I might get the TPB just to check it out (I really don't buy individual issues anymore).
