I thought in general it's good, but it has some specific shortcomings:
1. The acting is awfully stiff. But this is often the case for the first season of any show.
2. The characters mostly feel weak. They just don't come across as intelligent and competent individuals. This is a problem that occurs when the script writer lacks basic subject literacy or even interest - such as command structure, leadership, engineering, navigation, life onboard a ship, etc. When they have interpersonal conflicts it's often about puerile matters.
I do think it's worth the money though... so will watch the rest of the season. The CBS All Access (ad free) streaming quality, at least on my Roku Premiere+ with a 4K TV, is quite good.
