It was decent, but I fell this show hit every single sf trope in the first season - mysterious alien arrival, a crew mutiny, strange alien virus affecting everyone, an alien symbiosis and taking over the ship, a dream/alternative reality episode, a black hole,.... It was like SyFy greatest hits.
Also, every plant looked too much like Earth, they just walked everywhere without protective head-wear, like the air would be that breathable everywhere not to mention different gravity. I was irritated by the AI - I kept yelling at the screen - you are an effing computer program, not a person for heaven's sake, stop being so bloody emotional. The Earth story-line became dull halfway through and I just couldn't connect to the husband.
What I did LOVE was that everyone on the ship had at least one if not multiple replacements in stasis, talk about smart planing, though it would be wasteful if the mission had failed or if the ship exploded and you lost the top experts in multiple fields in one go. The acting was OK, i wasn't that impressed with anyone to be honest, they were all serviceable. The doctor wasn't confident enough for me, far to many times he/she was shocked, confused or confounded.
