Query: One of the best procedural shows.

Castle is a great character and the show is well done. Each season is an improvement over the last. I personally don't watch a lot of procedural shows. I used to but I don't have the time for the criminal or monster (in Grimms case) of the week. I switched to this show when I quit watching Criminal Minds & Hawaii 5-O.
