Like I said above, I'm all for villain redemption, but it has to be in the right place. I was so disappointed in how Krall's story ended in STB because that felt very pessimistic. He's given the chance to right his wrongs, has a moment of literal reflection, and then instead of pushing Kirk to safety and sacrificing himself to undo his mistake he just decides to go all stabby. How depressing is that as a statement about humanity?
There is room for a well-told story about the redemption of Georgiou, but nothing in season 2 showed any hint of it. That's my biggest issue at the moment.
