Fairly mediocre until the last few episodes.
The science is pretty much all over the place as far as wrongness, which was a bit disappointing. I eventually had to just sort of shut that part of my brain off. Characters are, for the most part, not all that well constructed and I tended not to like a pretty large portion of the cast.
The motivations and choices they make are...strange. There was more than one occasion where I thought the scene was going to be like a dream sequence / day dream just because of how odd it was. The AI was cool though.
I feel like a lot of this shows potential, as well as run time, was wasted. They basically could have cut out the vast majority of the middle, skipped to the last couple episodes, and just made more of that and it would have been far more enjoyable. Also, I guess they spent most of the budget on set design? Because the VFX are pretty meh. Oh well. Doubt it'll get renewed.
PS, the thumbs up is really only because of the concept and again, the last bit of the show were it actually gets kinda good.
