My expectations might have been high because I liked the premise and I'm a big fan of Choi Min-sik.

But oh man this movie was terrible. First off Choi Min-sik is totally wasted. Even ignoring the fact that the logic in the movie is waaaay off, this was just dumb. Basically it's saying that "extra brain capabilities" mean that you have super powers but act like a robot.

It feels like this was a movie made from a script written back in the 80s.

Not the worst movie out there, but definitely not worth paying for.
