They'll need to do some kind of big reset to explain why the science stuff in TOS is so far behind what it is in this prequel. Also why Spock, in TOS, says there's never been any mutiny in Star Fleet, when his own half-sister while serving as first officer on a ship in this prequel, was convicted of mutiny and starting a war with the Klingons.

There's also some seemingly stupid stuff that, AFAIK, they've not bothered to explain yet such as why sections of Discovery's saucer rotate in opposite directions when it's about to jump to high speed.

Discovery has a drive system that allows it to travel faster than any other star fleet ship in any other Trek series, but no one seems at all interested in installing similar drives in any other Starfleet ships - even though everyone is relying on this one ship to win the war - that seems rather odd too.
