No thoughts at all about Season One or Two, unfortunately, given that I haven't played either (curse you, lack of Macintosh support). I'm waiting for the Wii release.

However, from what I've seen of the trailers and videos, the humor seems to be the same as it was in Hit the Road and the comics. I wouldn't say it's obscure, excluding the occasional rarely used word, but it's a particular kind of humor which I suppose not everyone might find funny. I dunno.
