The plot was relatively interesting, but it was set up to resemble an episode far too much. I don't read a lot of media tie-ins, but there's a reason different storytelling techniques exist. This was almost like reading a beefed up screenplay.

However, Collins was really on the money with the interpersonal connection in the BAU team. The defense of Reid to anyone who would dismiss him as just a kid, the silent byplay between JJ and Hotch, Morgan's frank relationship with Emily- it's all there. This is actually why I kept watching Criminal Minds past the point where it got to be too much murder porn.

Pro tip: if there's ever a room in your own house that your man doesn't allow you into, refuses to the point of obscene anger - he's probably a serial killer. Sorry.
