I haven't seen it, and I've no BTS info, but I imagine it was like Star Wars Acolyte: it cost so much and ended up looking shoddy for the same reason - it's had the living shit reshot out of it. For reshoots, they use smaller stages and everyone involved has had less time to prepare, and it creates continuity problems when it's stitched back in with the original photography.
Typically, Disney knows when something isn't working, and their first strategy is to order rewrites and reshoots, and when that doesn't work (as is often the case), their second strategy is to seed the idea that it's 'woke', and use the predictable nerdrage from the usual grifters as cover for any legitimate criticism.
(I'm not being entirely serious with the suggestion that Disney seeds the 'woke' idea, but it's certainly so useful for them it'd almost be more crazy for them not to)
