Good movie, worth watching in theater.
Spoiler alert!
Movie could have benefited from an establishing scene in t the beginning to inform the viewer humans originated from alternate planet. I believe this is important due to the genre of space scifi has previously established time travel is possible and occasionally the result of malfunctions. Thus, the viewer may be confused as to weather the movie takes place in the past due to time travel or as it turns out, pre-earth colonization. Additionally a scene at the end with the main characters fate would have privided better closure. These scenes are likely left out due to other content making these deductions possible and to give the viewer some freedom to "write thier own" happy (or otherwise ending.)
Over all very enjoyable.
