This sentiment is by no means an absolute, because I loved the series from the very first episode and had zero expectations getting in my way, and I personally know others for whom the same is also true.
Season 1 of DSC is, for my money, the greatest and most completely satisfying Freshman series of Star Trek that has ever been made, and it only gets better with repeat viewings.
Likewise, as a kid I'd often let those expectations drive my enjoyment. I remember as a 10 year old walking out of
The Final Frontier loving it. Often, the more excited I was going into a movie, the more enjoyable I found it to be walking out of it. "The Sunken Cost" fallacy might explain things as I enjoyed it more because I had an investment in it. Therefore, walking out disappointed would mean I had invested my interest in it foolheartedly .
Anyway, a friend of mine took advantage of the quarantine to finally watch
Discovery after telling me two years ago he had watched a YouTube video about it that blasted it and made him think it was all garbage. He decided to watch Season 2 first, intending not to watch Season 1 at all. But after Season 2, he found himself interested in Season 1, so he went and watched it (more "Sunken Cost" at work, possibly, since he was in for the month of CBS All-Access already). He came away thinking Season 1 was better than Season 2. Not sure what that's worth, but there it is.
I also took advantage of this time to re-watch the show. I had intended to watch Season 1 for the second time before Season 2 last year, but never got around to it. I thoroughly enjoyed Season 1 upon my re-watch and am excited to dive back in to Season 2. I decided to watch all the
Short Treks (minus "Calypso" and "Children of Mars," the latter because it's for
Picard and the former because I think it fits better after Season 2) beforehand. "Q&A" obviously takes place before Season 2, while the other two Pike stories could fit before or after it.
So, at this point, I'm ready for my Season 2 re-watch!
