I LOVED this episode. It had everything I could ever ask and hope for in an episode of Criminal Minds. There was drama and tension, but they threw some creative curveballs into it as well.
I like how they ventured out to Denver to start off with. The drama was soo great in this episode. Where the last episode, Scared to Death, flopped since we knew the killer's identity right off the bat, this episode succeeded. It helped in a way kind of build an "understanding" of the killers and the cause of the damage they caused. It was nice to have one of the victims survive to in a way help with the investigation.
The acting was once again superb by everyone!
What made the episode really great for me was the end. I love how they did the creative twist with the guy giving the kid the gun. The scenes with Prentiss and Morgan hearing the shots and running to the house were phenomenal.
I also like the friendly interaction Prentiss and JJ had at the end.
