Probably my least favourite Trek series.
It was well made, well written, had a good story and premise and the acting was superb; I loved almost all of the characters.
The reason it only gets a middling 3/5 is because it kept building up to something epic that we just never got. The 2-part finalé was... OK I guess, but disappointing.
I've still watched it through twice, and I'll probably watch it again before the years out, but I am hopeful for better things in the second season.
