The premise of the story is good but the execution is just awful - sets, acting, script. It comes across like a TV soap opera and quite low tech given the time when it was made. I could see this as a series given they were only 1 year into the mission. Except for the people in hibernation event that leads to the death of Mead, the remaining plot points could used in a western.
Interesting, the guy with head in the glass had such a minor role. He was not allowed to talk to Earth -- why? In most sci fi movies these characters are the go to experts or the evil one but the majority of the action was not in the operation room.
It was devoid of the usual meteor shower or other external threat found in many movies and focused on the personal conflicts.
