I don't usually write reviews but, as I saw nobody really rated the episode yet, I want to say something about this episode.
I'm a big fan of Legion and today's episode reminded me, once again, why I love Legion so much. The plot, the effects, the drama, the suspance, soundtrack, everything was perfect. If you haven't seen it, I recommend you do it as fast as possible.
As I said in the title, this was the best episode of the season so far, in my opinion.
