This is not your typical scifi movie. Don't watch it for a realistic depiction of future colonization or some potential technology in our future society, no this is a poetic representation of space travel gone wrong. What happens when a catastrophic event occurs in the vastness of space? Again, it's not a methodical analysis of how humans would respond or the procedures that would need to be in place to safeguard life, it's a visual representation of the emotional response, and one done extremely well. It is has a slow pace, I think necessary to represent the experience of the characters themselves, where they have nothing but the emptiness of space and time.
