Indifferent, personally. Animations are a nice addition, but I've found that some of my favorite scenes in games sometimes have very poor animations (if any at all).
It's more about the scenario that makes it appealing.
Depends on the type of game, if it's a visual novel it's not needed as long as the still art is good, if it's not a VN then I think it should have some if it would add to the quality. But bad animation can take away the fun, so it's all on the skill of the dev.
Not animated are good, but if I can choose between two games to play, animated ones totally win me over. Even if sometimes I skip scenes cuz they're not that interesting, I still find them to be a good plus.
And if they have something like a cut scene, like 'After the Inferno,' I really appreciate those even more
Animations for sure if they're done well, but that being said, if a game doesn't let me skip the animation and have to wait like 10 secs before I progress I'm deleting that game.
