Having seen the first episode, I have serious reservations regarding the writing.
The whole thing was a bit too rapid fire - they desperately tried to shoehorn in as many characters and plot devices, leading to a somewhat confusing plot. I can understand some confusion as a metaphor for the federation's condition, but I fear that is just an overanalysis of writing that is... let's say it could use some improvements.
Given the smorgasbord of planned returning characters (Just about half of DS9's cast, by my estimate), I'm not holding my breath for any big improvements. Also, two/three episodes in and they're already bringing people back from the dead in some way (Alternate reality, time travel, Bajoran prophets/wormhole aliens (ugh...), lost sibling, transporter clone... Take your pick. I'm betting on the prophets.).
I also submit that any character whose name is spelled with double Xs is automatically a Mary Sue. Silly inner monologues don't help. In fact, I just realized that the captain's logs were a convenient way of doing an inner monologue-esque segment without adding too much disbelief that needs to be suspended.
tl;dr - Don't expect the world, but it's still better than Season 2 of TNG.
