It's not that the show is babyish that bothers me, it's that everyone in it is an idiot. DW's the most annoying little prick, Arthur & Buster are dumb, Alan/Brain ain't too smart at times, Francine and Muffy are conceited bitches, Ratburn's a hypocritical shit, Dave and Jane are ridiculously stupid parents, Binky and the tough kids are stupid...everyone in that show, except maybe Pal (I love dogs) makes me vomit.
I know what you mean! I've fallen back in love with Arthur after about ten years (I've watched it since it debuted, and now I'm twenty). ^^ I'll have to watch out for your doujinshi...I have something in the works as well.
