The ratings have been better this season, thanks in part to Jay Leno, and it seems to me that the chemistry between Fillion and Stana Katic is stronger and less forced than at the start of the series. (Or perhaps I've just gotten used to them.) I still don't love the mysteries, but they've gotten better at coming up with the sort of hooks that would intrigue a guy like Castle - what mystery writer wouldn't want to work a case involving amnesia? - and the plotting is mostly an excuse to let Castle annoy Beckett for an hour.
If you're watching, what do you think? Any areas where you feel the show could improve itself? Or do you just like Fillion enough that the rest is window dressing?
