Air

From the first scene you are thrown into a reality you don't understand. As the movie progresses and little indications make the setting more clear, you still are left with a feeling of missing elements that really don't allow you to fully comprehend how the characters got to be where they are. Ultimately, this is somewhat a moot point as the entire struggle of the movie centers around the characters capacity to maintain adequate air supply for their survival. Overall, the movie progresses slowly and doesn't fully ket you into its world. Those facts make it pretty hard to maintain focus and attention for 40 minutes let alone 1h30. Not recommended.
