Excellent movie, but the trailer was misleading - SPOILER ALERT!

Rating: 10/10 (29 December 2016)

WARNING - THIS REVIEW CONTAINS SPOILERS! The movie was excellent, being perhaps the first real combo romance-science fiction movie ever made. It did so with mostly plausible events, as good as most science fiction writing. I never expected Hollywood to do as well as "real" written science fiction. And Jennifer Lawrence was superb, as can only be expected, and so were the special effects and the space-ship itself.
But the trailer was misleading. At the end of the official Trailer, Chris Pratt says, "there was a reason we woke up early" which makes it sound like there was some kind of a conspiracy, or perhaps aliens on board wreaking havoc, or a corporation cutting corners. This led us to think that something "more" was going to happen on the ship. Instead, the cause of them waking up early was simply a prosaic accident of nature. My wife was very disappointed because she expected something a lot more treacherous cause (human or alien life form) than there was, due to this misleading trailer.
There were at least two other major events which were scientifically impossible too, but I am willing to forgive those since it was necessary for the sake of the story.
