Much is the case for Diablo games. They do a great job of setting up lore but are dog shit at executing a good story.
I liked the first two in this regard because of how simple they were. You basically fill in the gaps that some grim .. as fuck cinematics present you with a general idea of what's going on. The original especially is carried hard by its atmosphere and presentation with sprinkles of heavy, dark exposition of lore throughout and an ending that is fucking bonkers dark. If you strip it down to essentials, yeah it's simple, but there is beauty in simplicity. Diablo II went a little farther with exposition in-game, i didn't really like that, but it was such a massive improvement on all fronts while also retaining its ridiculously grim cinematics and atmosphere. Diablo III screwed the pooch by going all aboard on story, and the writing and storytelling was just so bad. I loved the cinematics, they work fine as is without all that shitty context in-game because they're epic.
Diablo IV looks like some of the same, but an even more stronger emphasis on story. I'm sure i'll love it, i just love the mythos of angels and demons, even if the in-game story dump will be shit, the cinematics will carry it hard. What i'm worried about is the loot itemization and lvl scaling.
