The show's kinda hit-or-miss, I think. 1, 3, 4, 7, and 8 have all been fun, but 2, 5, and 6 didn't do much for me. But then again, they can't all be winners, right? I'm loving this show's version of Zenigata, though: tough, badass, intelligent...but still prone to Lupin making an idiot of him. Actually, all five of the main characters have been portrayed well, and I really like the new characters, like Rebecca and Nix.
I do have to admit that the show seems to be a bit more realistic than the other three, with little of the slapstick or outright lunacy that I've come to love. I guess that, in a sense, it's more of a sequel to Cagliostro than the other three TV series, but I'm only, like halfway(?) through it, so maybe things will take a more Monkey Punchesque direction?
Nevertheless, despite my nitpicks, it's still a fun series, and I'm enjoying it.
