IMO, the best way to appreciate "The Lunatics" series is to not even consider these guys as Bugs and the old gang. Alternate universe thing. Kind of like Buster and his group. And the baby Looney toons stuff. Each is good in its own way, if you don't compare characteristics. Otherwise you go into it thinking "Bugs would never do that". And you'd be right, and hate the show.
Ah, I watched an episode, god was it terrible. I was thinking it might be passable, like Duck Dodgers in the 24½ century, but it wasn't even that, the plot is convoluted, the sense of coolness they are trying to embue the show with is forced, and all in all it sucked greatly.
