Its actually true when they say, if you don't understand it you probably wont like it. Maybe this could spoil a little bit the movie, but it's necessary to allow everyone to understand the movie, making them aware they failed the thought experiment! My assessment for the movie is actually positive. It's not exempt of flawless. Maybe the narration is too focused on some sex scenes and even visually ones which could be effectively removed without changing the story and keeping focused the audience. Even the questions raised during the lecture where debated too briefly just because to give to even the most ignorance spectator the tools to solve the riddle! Moving beyond this flawless and reviewing the story you can easily understand at half the movie that the thought exertion is not only requested to students but even to you. The envision of the apocalypse was not less than their life! The big question which is at the basis of the movie is: WHO WILL YOU TAKE WITH YOU DURING YOUR LIFE? Will you surround yourself with smart people, intelligent, maybe scientists just to purse higher objectives and catch all possible opportunities but keeping emotions, amusement and recreational experiences out of your life or will you live your life like a human being? Not only making it dominated by logic but even emotions and precisely philosophy! The thought experiment at the beginning is carried only in one direction but soon, the smartest among them! Realize that there is something more! something that the professor is trying to force them to leave. The final is simply the realization of the importance of what you will put in your life, your loves or just your work accomplishments... Now watch again the movie and keep in mind all those things, you will start to debate even on your own life, not only what choices are made by the students in the movie...

I admit this wasn't exactly as exciting and fast paced as the trailer suggested but I still really enjoyed it. While everyone seems to be slating the film for its explanation of philosophy I think they are missing the point. Personally I believe the film is more about human nature and how in essence we are emotional creatures. Here is a tutor arguing about logical choices and not allowing emotion to guide you when in the end it is revealed the whole exercise was created as his emotional reaction to something. I cant say much more without spoiling it for those who haven't seen it. I would definitely recommend this to others. I would call this a Sunday afternoon film, it does all the thinking for you but you can still enjoy the ride.
