See, I am the exact opposite, and most of my family is. They don't mind knowing the scores, and don't actively go about avoiding them. My dad will revisit old games and films that he likes, regardless of spoilers. I tend to be the same way, as I prefer to see
how something happens, rather than just the facts. Likely comes from my tennis playing days
Prequels are a whole different animal than most sequels, though the Star Wars sequels are falling in to that territory too. More on that in a moment. Sequels just continue the adventure, and more successful sequels will do something than the original film material-see Aliens, Empire Strikes Back and Terminator 2, among other examples.
Prequels play with individuals expectations and emotional investment. The characters might not fit with what we imagined them to be like, or how events unfolded. For example, I had imagined how the Vader and Obi-Wan fight and how Vader had gotten burned long before seeing ROTS. It certainly wasn't how I imagined it when it was put to film.
Likewise, the TOS era had already had some imaginings, with FASA, novels and individuals imagining it, setting up expectations for what came before. And, unfortunately, those expectations cannot be met. It's just not possible.
So, when individuals say "It doesn't feel like Trek" I'm starting to get that, because it doesn't meet those imaginings that went on for a while. It can't fill the gap of nearly 50 years of ancillary material, technological developments and societal changes. It's a challenge, that ultimately will
vary from individual to individual, based upon expectations.
For me, characters will always matter more than story, more than continuity and more than art design. Regardless of personal imaginings, I love seeing variations on a universe, and DSC does that well, both with characters, setting and design work.
But, prequels are not for everyone and I do understand that.
