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.

The film's core idea is smart enough, but the application runs into several problems. The first iteration of the thought experiment is promising, and the idea of multiple tries is good. You know, if you forget small things like that the rigged cards are obvious to everyone but the very clever students about an hour before someone suspects something. But on the second part, things turn sour. Things happen in the bunker that simply can not be justified: who decides the gay characters have sex only to be seen by Petra, and then actually argue about it? (!) How does one of them (and then again in the third part) hide in a room? It's absurdly arbitrary. On the third version, we get a supposedly top student make really, really poor decisions based on some kind of naive Christian-hippie attitude to life. Granted, she is doing it to annoy the teacher, but it doesn't help that people are falling for tricks such as "come really close to get the keys so I can pull you in - oh man, I can't believe that worked!" or "I stole your gun by pretending to care!". Internal lack of coherence such as "I remember the code I might have seen you type in an imaginary past life" is also a sign of poor problem solving by the screenwriters. Who seem to realise that their characters started taking things too seriously and try to release some comedic relief and more backstory in the end. The first fails, because it's neither very good, nor very well balanced, it feels more like a sudden change of direction. The latter kind of helps in establishing that we don't have a vengeful genius (=evil) teacher who likes to torment his students. All in all: it could have (perhaps) been better if it was a fully serious film but with more careful scripting, or if it was far less serious. As it is, it's simply decent.

PS. If these students don't understand that Mr Zimit is right about pretty much everything, they may need to repeat the class.

PS2: Babbling on a bit, but I have to say, in the first attempt at this experiment, if I was among the outvoted, I'd use the "5 minutes to be alone before everyone enters the bunker" to tell the rest of my group to run inside and shut everyone out.
