And, I think this highlights a key reason for the differing opinions about a prequel, or actually a midquel. I can completely understand that, if you don't care about those larger aspects, a well executed sequel will not take anything away from you. However, if the world (galaxy) building aspects are important to you, then you do lose something with a sequel.Those were things that I honestly never cared about. Besides, the novels should go on unaffected by Discovery.
It's just a preference and one isn't inherently better than the other. You can certainly tell great stories in either a prequel or a continuation. I love the time frame. In fact, if it had to be a midquel and I got to choose the time, I'd probably choose this exact time.
That said, I'll miss the larger world building possibilities. While there can certainly be conflicts between the various big players, it's all got to be reset to what we know happens in TOS.
