Ok.. This episode in so many ways was very contraversal but I think there was quite much I really liked. The new depth they got to Rossi's char. You never imagined something like that from him but even with that way, with his past, they managed to turn it all into quite positive ending. I mean, the final conversation he had with Hotch in the plain, it had really good and beautiful point.
I also loved the dark tunes and very dark color schema used in the episode. Also some really great camerawork, blending from one scene to other. And the switch in the end, to see the irishman killing that hitman, great twist.
I think in some way this episode lacked little what I love about the show, but it was different and it wasn't bad. It was high stake case, a very random at first and catching.
