TV drama in our day and age focuses almost entirely upon character. Plots are basically soap-like, and do not alter the political landscape of the world to the degree that Babylon 5 did to it's world. Instead consequences are measured almost entirely in characterization. They call it the 'Golden Age of TV' and the 'age in which TV has surpassed cinema as a medium', because people really go for this kind of complex character based drama - and it has allowed unprecidented levels of acting to emerge, such as Bryan Cranston's performance as a villain.
You have to understand the context that this show is being made in. The context is that Trek is being updated for this 'Golden Age of TV' - the era of Netflix-exclusive series - the era of season-long arcs. It is probably being made as a 'modern TV drama' - in other words, the acting/character-based/dramatic consequences will probably be emphasized to a degree never before seen in Star Trek - closest to DS9. The exact type of 'character-only' consequences that you would prefer they were not doing.
But people will love it - because that is the way of modern TV - to focus upon angst and turmoil and psychology - and quite honesty, if you look at early TOS - there is a good argument that it's been a part of Trek from the get-go - the whole point of episodes like "The Cage", "Where No Man Has Gone Before" and "The Man Trap", etc. Look at how "The Man Trap" ends with Dr McCoy having to kill a replica of a former love interest, being shouted at to fire, while it sucks the life from Kirk's face - I believe that is what we will see from Fuller, and I'm game for it! It might be best to accept DSC on it's own terms, rather than want it to be Babylon 5 or Farscape or SG-1 or BSG.
I think you really have to embrace it for what it is, or you will be disappointed. Find the joy and interest in this type of storytelling. I think there will still be lots of plot, but no, there will probably not be some existential threat to the Federation that we don't already know will fail - the story will be how much suffering is inflicted before that threat is vanquished - or how an untold part of the Klingon-Federation Cold War unfolded - or how a defector and spy has their assumptions and life destroyed. We may well get a show set in the 25th century in the next few years, but I think for now, this is the approach that will be explored.
