I've had a feeling the Borg would come into this, and the timeline sort of fits in. If Control somehow get's jettisoned across to the Delta quadrant, that gives it what, 100 years to get going and get involved in the Next Generation timeline?
In general, Discovery is up and down. The stuff with the spore drive, Stamets & his relationship is fucking horrendous (and no not because he is gay, but because its boring AF). Burnham is IMO not a great central character, and am still wondering how they can tie her existence into 50+ years of Star Trek cannon with no mention of Spock's sister (unless via more alternative timeline shenanigans) although I think the actress is fine. The human/Klingon guy was getting tiresome but they've eased off that conflict a bit.
Pike is the highlight and his scenes in Episode 12 were for me some of the best in the history of Star Trek. The look of the show is also good (esp now the Klingon's seem to be starting to look like cannon-Klingons), and I don't mind the general over-arching plot of Season 2.
If they could do a soft-reboot of this with Pike as the focus, no fucking spore drive, and Burnham as a capable human raised by Vulcan's but NOT Spock's sister, the show could be vastly improved IMO. In fact, make it TOS in the years before Kirk took over.
