Why does Disney reusing animations in the past matter? Previous Sims titles had so much variety in animations and there's no refuting that. And since TS4 is apparently successful, they could do the same for this game. But they don't. So I will rightfully find reused animations annoying. As someone who plays while taking a lot of screenshots, there's less animations and facial expressions I can use because 5+ of the interactions have the same animation. Granted, I'm not as annoyed by it as some other issues in the game like your Sims constantly wanting to sit in chairs when I want them standing. But it's still annoying nonetheless.
Heck, I find it absurd your Sim can't sit while playing the guitar.
