Re: "Castle" season 4 begins tonight
I dunno if I would totally agree with that. Castle seems to have been pretty consistently written through the first three seasons as well as his personality intact. The show has never really taken its self seriously to begin with and has always been tongue in cheek with Castle's theories and the plausibility of the various cases that Castle and Beckett investigate. I mean the show's main arc is the murder of Kate's mom and we've since learned as the show has progressed that it seems to have been a part of a conspiracy.
