I give this 2 stars. The production quality and effects are very well done. That’s about it. Like all the science fiction shows of the past ten years it purports to be realistic, but as usual is not. Astronauts spend years together training for missions and if there was any friction they would be pulled from the mission. The astronauts take take stupid, unnecessary risks. For example an astronaut doing a space walk would have 2 tethers at all times, would never remove them both, and would NEVER take risks or matters into there own hands without clearance from mission control. After watching two episodes, I came to the conclusion they should put the Indian astronaut in charge, as he’s the only one with a brain, the rest of them should be sent home before they get themselves killed.
