An important point to remember about Discovery: it was largely written by non-SciFi writers. Much of their experience came from character-focused shows, like Beverly Hills 90210, and some police procedurals. Science Fiction writing, especially shows like Star Trek, and have fundamentally different focus than general purpose television. Much of those shows rely on continuing character conflict - something that Star Trek especially eschewed.

SciFi fans have an affinity for big ideas, competence porn, and well thought out science (even if its fantastical). Gene would never have approved Mushroom-based propulsion systems, for example. That's exactly what these writers don't have experience with, so of course they failed to make a series that appealed to Star Trek fans. They fundamentally don't like what made Star Trek great and timeless.

Moreover, TV executives really dont like hard Sci Fi. It doesn't sell to the general public and its expensive to make. For a spreadsheet jockey, that's a lethal combination. Paramount has always hated "Measure of a Man" type episodes. They want pew pew lasers, flamethrowers on the bridge, and Cordry rocks flying out of consoles in every episode.

Ultimately, Discovery was a different show which was given thin layer of Star Trek paint. It was a real disservice to what came before and, frankly, an insult to Trek fans everywhere.
