The DISCO creators were up front that this show would be about Burnham as the main character and they mostly followed through on that, so I don't get why some people seem shocked by that. I can see if some people don't like it, and it wasn't seamless, but Burnham as the lead was how they intended to go. I don't buy the Burnham praise chorus stuff so much because the first season showed her screwing up and having to redeem herself. It explained why Georgiou, Lorca, and Sarek had attachments to her, and why praised her. It just didn't say that Burnham was super awesome and leave it at that. She faced challenges, and for a brief period almost all the Federation hated her and she hated herself. Burnham, while getting praise, also got a lot of ire coming her way on the show.
I think DISCO was trying to be different than other Treks and there's nothing wrong with that. They didn't want to do the ensemble thing as much as in TNG, VOY, and DS9, and to a lesser extent in TOS and ENT. However, older fans-like me- might have not have adjusted well to that different approach to storytelling. In any event I think the end of Season 1 had a more ensemble feel and from what I've seen/heard about Season 2, it will have more of an ensemble feel, though I take it with Spock being involved and the Red Angel mystery, this will keep Burnham at the center of the show, as it was long intended.
I also think that when it comes to criticism of her being good at a lot of things, this follows in the footsteps of many Trek characters. Kirk was the youngest captain-at one time-and a walking library-who flouted orders with little repercussion throughout his career. Spock was a living computer pretty much. McCoy was one of the best doctors in the fleet, etc., etc. We saw this kind of stuff on the other shows as well. (Re-watching a little of Discovery and Burnham at times reminds me of Seven of Nine even). And when we get to ENT, they don't even try to justify why Archer is captain outside of his dad's accomplishments and him being friends with Admiral Forrest, and throughout the show we hear stuff like he is the greatest explorer of the 22nd century and how good he is, but IMO it was rarely shown on the show itself. I came to accept Archer, though only during the Xindi arc because of how they tested his character.
