It looks like a generic cash grab title you'd find in Walmart that's ripping off the The Book of Life yet somehow has a bigger budget.

I think it comes down to the character designs. Pixar settled for something between too human and too cartoony. It's uninspired design. It worked in Monsters Inc because Boo was one of the few characters in a movie with mostly fantastic beasts. The Incredibles worked because their characters had exaggerated features. But here, they chose designs that just look off. And they somehow all have the same skin tone that rubs me the wrong way for some reason.

And as an aside, one of the pitfalls of Pixar as a brand is that they have a core audience that's aging. Kids in the 90s are in theirs thirties now. Their movies aren't again with their audience. Their target demographic remain children. They need to readjust their own staff to reflect that somewhat. Illumination, for instance, has a fairly young audience via the Despicable Me franchise. DreamWorks... Is a mess. Their audience skews older but there movies have been dreadful for the most part by being the anti-disney and never found their voice. Shrek 2 is a classic but the other two sequels were just terrible.
