Wonder Boys

Why did they make Wonder Boys this way?  Katie Holmes tell the guy from Wall St to stop smoking pot to write better, he does but the then in the end he is turning out drivel, sitting at his laptop like a douche.  Was it supposed to be that kind of commentary?  I think I would rather be the guy in the pink bathrobe churning away at the typewriter with a 2000+ page book than sitting up in that attic, all cool and collected.  I guess he does get Francis McDormand and a kid, and maybe that's what life is all about.
