I really love tokyo ghoul! reallyyy...
So I was super excited to see this live-action, but with some obvious fear, due to the Attack of Titan movies that have scared me.
However I have to say that I loved the movie itself. From how they built the story, the actors and even the special effects, it was very good.
Masataka, surprised me too, I even felt that it was Kaneki with that innocent and aggressive side when he is taken to be, I could feel that it was really him and I just want to go in and hug him and say that everything is okay, we was such a character so I was impress for the act. The others were good to, I wanted to see Uta so bad *lol*

Overall I liked it a lot and I think you should give it a try, both the story and the filmmaking went very well. I can only hope for another great movie.
