None of those things are 'reinventions'. Those are called story arcs.

Season 1: Had a shuffle of show runners and was the first season of a Trek show. The vast majority of Trek shows don't find their footing until Season 2 or 3 so I feel like this is a non-issue.

Season 2: 'Palate-cleansing memberberries' is not even remotely a fair summary of the season, especially when half of the stuff you're talking about were barely in the show. Spock doesn't properly show up until halfway through the season. Moreover, the show takes place 10 years before TOS. NOT including the Enterprise in some capacity and showing off Captain Pike in his prime would have been whined about. It's also kinda hard to suggest that it's nostalgia for the sake of nostalgia when Pike was never a large part of TOS or the Star Trek world in general. Una straight up never had a name until Discovery. They brought aboard the least well known Enterprise crew and a broken Spock. Hardly 'memberberries'.

Season 3: The timejump was planned from Season 1, so no. It wasn't a reactionary reinvention of the show to what people did or didn't like. Going home couldn't have been a serious plot consideration because of the entire arc of Season 2. Also "Burnhams mom is the only character that matters until Season 4". Right. I guess the whole thing with Saru and his arc (which you literally just mention at the bottom of your post) doesn't matter. Guess Adira and their arc doesn't matter. Guess the Trill being set up doesn't matter. Guess President T'Rina of Nivar doesn't matter despite her being a major player in the following seasons. You either straight up did not watch the season or you're misremembering so badly that your summaries here are just not worth anything.

Season 4: Sonequa called it a new start for Burnham. Moreover, what do you expect it to rehash the same shit forever? They're in a new century and after the ending of the last season it's a new start for the FEDERATION as well. Once again you're actively ignoring half of what's going on in the season to fit your own personal dismissive narrative.

Season 5: When the season was written they did not know it was going to be the last season. And once again you actively prove that you either did not watch the season or barely paid attention. There is a literal time jump in the season showing what would have happened if Moll 'won'. Burnham saw a timejump where Moll and L'ak won. FedHQ is in utter ruins and the crew is dead. So... no. Really don't think that would have "worked out better".

You just spent a message dissing the show and inaccurately summarizing aspects for the sake of insulting it. So...

Overall I liked Disco

P.S. It is hysterical to suggest that DSC was reactionary in any way when every single season pissed people off worse than the last and doubled down on the core tenants and messages.
