A pretty great episode all around. I enjoyed the storyline. It was very interesting, eerie and had a bunch of turns that kept me entertained (i would list some of them, but i dont want to give anything away). The only problem i found is that the team received a big clue when Morgan and Prentiss looked at the stars. it was too random and lucky for the team to to catch the killer based on two members looking at the stars. Other than that, i was thoroughly entertained and i would recommend this episode to any Criminal Minds fan.
This episode earns a 9 out of 10.
