I normally don't review movies, but for this one I'll give it an attempt,
OK, so the movie starts off, right off the bat it grabs your attention, as a group of 50 presumably present day humans all wake up in a room, at about the same time standing in a circle within a circle, and within the first 15 minutes the rules become clear, yet the purpose is unclear, is this the CIA? ALIENS? No one knows
Anyways if you step out of the little circle your standing in you die, but people start dying every two minutes, and they soon figure out its a vote,
The movie basically explores the human logic and emotion when faced with death, and the will to survive, the people basically have to vote eachother off every two minutes so it's basically a who will be the last one standing as presumably the last one gets to live, now some of these reviews say the characters are stereotypical, with no real character development, and in a normal situation, that would be a fair criticism, but keep in mind they only have 2 minutes ea h time to decide who dies next, so I forgive that aspect, because it's time sensitive, I'll also will admit this is probably one of those movies you'll either love or hate, I understand people's criticisms, but I thoroughly enjoyed it, yet can see how others didn't, anyways it's interesting enough that I wouldn't mind seeing a sequel or re-watching this one I'll stop here as I don't want to spoil the ending... Definitely one I would recommend but keep in mind it is more of a thought experiment then a regular Movie, but worth the 90 minutes to explore I gave it 4 stars because I really enjoyed it, it's my type of flick...
