In retrospect, I was too hard on discovery. I did end up liking most of the episodes, and I regret that it's now over.
I really liked Culbert's quote of "there is a beauty in the mystery" - which I instantly reflected on. I think too many people need "all the answers" and it's nice to appreciate when something is beyond comprehension (well, that was my interpretation of the quote).
I also liked cook's comment of "Future is a scary word" - and I think a lot of people feel that way right now (especially with Discovery ending!) - I was a different person when this show started and i'll be a different person again in another seven years.
Finally, I liked that the progenitors didn't create the tech, and they didn't have all the answers. I think this was a good move on the part of the writers, I also like that the tech was left in a state where it could potentially be found again if the plot needs it.
If you asked me a year ago, I think I would have said Dr. Culbert is my favorite character, but Commander Rayner quickly won my admiration, and he is my favorite by far.
