I think there’s a lot of potential.

You get a couple of episodes to get attached to the Deltan character before she gets killed off. You get about four episodes to get attached to Fuzz before his betrayal, which would actually give it some weight. You can actually spend some time exploring what it means for San to have crossed over to the Prime Universe, and how it affects Georgiou (and maybe explain why isn’t way older than he appears to be, that’d be nice). You get enough time to make Garrett’s arc actually work.

It really seems like ten hours of story stuffed into a two-hour bag.
