I honestly say that Liar Game 2 Season2 isn't worse then the first part. Both are on good level. Unpredictability, tension, misterious rival Shinichi and Fukunaga without a sense of style.
Nao gives me a headache again. I though she learnt life a little if she started cheating too, but nooo....
I miss Yokoya... he was such a curious human. Katsuragi Ryou can't replace him. In my point of view, the confrontation between her and Shinichi was just unfair, because the main character was using the BRAIN, but she was winning only thanks to MONEY. I know - Liar Game, however, she could be lost without cash.
Hmm.. this season is strangely divided. There aren't the final stage, but we need to watch the movie. Really, they could make just one story.
