I don't think the 'audience' ratings can be fully trusted though. Any new film or TV show these days with prominent women, minority or LGBTQ characters (Discovery has all) gets routinely review-bombed by alt-right participants who likely haven't even watched it - that's just a fact of these ratings. My anecdotal discussions with irl Trek fans didn't find the same antagonism to Discovery that you find online.

Discovery wasn't the best of Star Trek, and I ended up switching off early Season 4, but much of the early hostility towards it was either that sort of bad faith, or focused on trivia (which leads me to wonder if it was just cover for the same - I cannot get my head around people who refused to watch because they didn't like the Klingon prosthetics).

Season 1 was solid, Season 2 was arguably even better (although owed a lot off that to Captain Pike). Season 3 had great promise in its premise but failed to realise it's potential, and then Season 4 just felt lost.
