Yes, there should be an option to skip the dice roll animation in the Settings menu. The player still needs to see the result of the roll, so it could be replaced with a red "Fail" or green "Success!" text at the end of the dialog choice. I'm not sure the player even needs to see the number rolled vs. the target number. Anyone who really cared about that could use the animation option.
I get why they're doing it this way: it builds tension and anticipation like rolling dice in real life. I would probably keep the animation because I like to take my time with this kind of game, not rush through it. But I can understand why it's annoying for some.
The D20 crit animation on the other hand, should just disappear unless they can do it better than this. I wouldn't mind an XCOM type kill animation if it's well-done, but they don't seem to have a handle on it yet. And it should also be something we can opt out of, in the settings menu.
