Caste 5x7 - Swan Song
Kind of on the fence about this one. It was fun, and I did like the murder storyline, but I've never been a fan of documentary episodes and shakey camera angles. I will, however, admit that every time Castle said "Fade to black, musical sting!" followed by him singing the classic Castle guitar riff made me chuckle. Every time. And I did love them all singing at the end, because sometimes I like it cheesy.
