So this happened today...
To be honest I was already expecting it to be violent from the trailers' I'd seen but wow was this a disturbing movie. If you watch it you'll understand what I mean from the very first scene... I was sitting and about to enjoy my movie snack and then completely lost my appetite less than 10 seconds into the movie haha.
But though violent, it was quite an amazingly filmed and acted-out movie. Toma was so flawless in his portrayal of his character it gave me the creeps at more than one point in the film!
There were plenty of utterances of 気持ち悪い and ドキドキした afterwards but I think it just means the film was effective. Definitely go see it if you think your stomach can take it! :D
