The movie has several plot holes, but still enjoyable

Rating: 7/10 (4 January 2017)

I enjoy the whole movie and don't feel bored at all, so I'd say it was a good experience, although some questions struck me while watching the movies. nevertheless, this is a good movie overall.
SPOILER:
There is no way there is no manual override for such critical procedure (hibernation). Also, no redundancy system, say, for burned chip? they should create a better plot. 5000 passengers, 258 crews, 1 autodoc. really? so when they all awake 4 months prior landing, it would be a disaster. i have more questions but those are the ones that struggled me the most.
