I loved Jeff Russo's main title theme to Counterpart but I have to admit for me his work on Trek (DIS, PIC, SNW) has depended too much on an awkward (to my ears) bookend structure where he:
starts with a familiar Trek motif
introduces new theme or a variation/development on a Trek theme
ends with a familiar Trek musical motif
That said, given the premise of SNW, it's more justifiable for that show than the other two.
