This movie gave me mixed feelings after I finished watching it. It is a good thriller movie that keeps you stressed from its beginning till its end. However, it has its drawbacks and cons. My review will be neutral and summarised by mentioning the pros and cons of the movie, in my opinion.
Pros:
1. Good thriller that puts you under stress and keeps you awaiting for what is going to happen next.
2. The concept of the movie is exciting and painful at the same time. It is one of these movies where you fly with your imagination and make you think how you would react and survive if you happened to be in the same situation.
3. Good outcome of limited characters and space.
4. Some events in the movie were emotional and dramatically affecting.
Cons:
1. The beginning of the movie was too short for me to have my feelings engaged and attached to the main characters of the movie. I wish they had spent more time and gave more details in presenting the relationship between the main characters.
2. The acting of the main characters was kind of weak and did not reflect the magnitude of the calamity in the movie (facial expressions, reactions, decisions, etc.).
3. Some events in the movie were illogical and unrealistic.
4. Snickers advertisement?
Overall, this movie was not a bad experience. If you are looking for a movie that has the pros I mentioned and can ignore the cons, you will definitely enjoy this one.
My actual rating is 6.5, but there is no "half" on IMDB and this experience was more good than bad to me, so it got a 7.
