This episode was spooky and creepy in all the right ways. It was certainly a very week different one than we get each week, and I really enjoyed it. It was weird and unusual, and it was backed by an interesting concept.
The unsub was suspected as a team of a man and a woman, then it turned out to only be one... or did it! The multiple personality disorder thing was really cool and I think they executed that really well!
Keep it up, Criminal Minds! I can't wait to see some more really great episodes, and I would highly recommend this one! Great job, please keep it up!
