If they were divorced couples

Rating: 7/10 (31 December 2016)

The movie's script can be better, if changed to this plot：
The man in the spacecraft was accidentally awakened, who had been divorced for some reason. However, he awakened his ex-wife due to loneliness and refused feelings. after all, It is about 88 years that the whole journey need to take to the destination, which is equal to ruin the woman's life. Because of the past contradictions, they were quarreling and fighting with each other. At the time when calming down, they were considering whether to wake up their two 10-year-olds. Then the problem arose. Waking them up, it is would equal to the destruction of two children's life. When they will be in adulthood, the two children may hate their parents in the spacecraft over their lives. Not waking them up, the two children may hate their parents because parents did not wake them during the journey and other children go to their homes in new world. This situation has risen to the philosophical choice, which needs the parents to choose. After solving the problem, this movie can follow the original script to carried out.
If this 90-year journey is really to achieve, I suggest the system of rotation。During the whole journey, no one control the spacecraft when the crew has been hibernating. This situation is not consistent with common sense. If the entire spacecraft is fully automatic running, it would possibly have no way to automatically repair itself when errors occurred. In this case, the spacecraft should have been arranged to take turns on duty staff. For example, 10 crew members are on duty in each decade when the rest of the crew are hibernating. When this 10 years' job is over, the 10 crew members must return to the cabin aiming to hibernation. At the time, the other 10 crews will be on duty.
