The creators obviously set out to make a movie similar to Alien or The Thing, but centered around a thoughtful scientist instead of an action hero. The result is a slow burn that stands far above similar sci-fi movies but the pacing may not be for everyone. Ultimately I enjoyed the movie but have mixed feeling about the ending. A spoiler free way to put it would be this: not how I would have done it, but true to the character and I'll give points for consistency.
