This is one of the best episode of the season.
Micheal Rosenbaum is really great in this one and deliver an outstanding performance. I adore those kind of movie that make you question yourself is he crazy or not? Is it all in is head. Like Shutter Island, Shattered is very well construct, and show a side of Lex that we didn't saw a lot in the show until now.
The ending scene with Johnny Cash - Hurt is a masterpiece. It's worth easily a 9.8/10.
