90% Great; 10% Suspension of Disbelief

Rating: 9/10 (15 May 2017)

This movie was not Alien. Don't go in expecting Alien. This was a different movie entirely.
Character development was solid, acting was believable, the story kept on trucking. The monster was scary as hell.
This film really only suffers from two things.
The first is that the story mentions, but doesn't clearly articulate that this was a privately funded mission, held on a private space station. A lot of the disbelief comes from our assumption that every character should be prepared for every eventuality. That's how NASA operates. But for the most part they act like people who are experts in their respective fields, but have no training to deal with things that are outside the scope of their expertise. It's the "Doctor in a fender bender" scenario dialed up to a 1000. And it's totally explainable with a more clear emphasis on this not being a military or government operation.
The other thing is an attempt at a gotchya moment at the end. It just wasn't handled well and was entirely unnecessary. The whole movie masterfully handles suspense and fear without any of gotchya moments and they could have closed out in the same fashion.
