One of the big complaints about S1 was that they tried to go for a full bingeable season arc, with everything tightly tied to that story. It was a deviation from what superfans thought Star Trek "should be", even though it's a shift that TV as a whole has really made, not just Star Trek.
This season is their attempt to play it both ways. IMO, it would have been better to establish the Red Angel stuff early, and then have Discovery continue their mission because they're at a dead end, and then a few episodes later you can have another red spot show up and base the episode around it. Instead, it feels like they've got unrelated storylines they keep whipsawing between every episode and it's a problem.
I mostly like the one-off storylines. The Red Angel stuff just seems like it's trying way too hard to be a "thing". That's due to weakness of the writing, because they just slap it in around the main actual story of each episode.
Doesn't help that it's almost definitively a deus ex machina device.
