This film is very complicated and difficult story I have ever seen. Secret agent that has advanced technical skill gets into people's dream to steal other people's ideas. One day an impossible mission comes to them and try to succeed the mission "Inception" In the ending, we need to guess what's going to happen. The main actor is Leonardo Dicaprio, and from Japan, Ken Watanabe acts the most important role. As I said at the beginning, it is too hard for me to understand the story completely, because this story shows the real world and future. I sometimes did not understand which world I'm watching. I watched it with my friend, so we asked each other "Is it a dream?" like this. However, it is very high quality so that I could not follow the plot of the story. If I were clever, I could have got the story! Totally it's worth watching, so if I can, I want to watch it again.
