Yeah, this movie looks problematic. I generally can't stand sci fi movies that try to push a story of a psycho astronaut. The astronauts generally go through enormous amounts of vetting to make sure they don't send up someone who could get himself, and the mission, in trouble. I'm reminded of the SUNSHINE film, and PROMETHEUS, where the crew is chock full of whiny, petty, self-centered brats, rather than professionals.
