I've only watched the first four episodes but I don't expect the show to get any better.
Murphy's Law comes to mind: Anything that can happen, will happen.
Except in this case it has been modified to: Everything that could possibly happen, does happen.
Otherwise. I'm not sure how this mission was even authorized. We have an astronaut who is known to have killed 10 people in a previous mission...and this person is leading the mission? There is a Political Officer who has never been in space before? Nobody likes/gets along with anyone else on the team?
The only part that is believable is the self-absorbed reporter who is claiming truth in reporting so she can ruin everything to up her ratings.
