As an animator myself, I find it beyond disappointing the amount of reused animations within the entire game. Similar animations would be one thing, but reusing completely identical animations for multiple different actions is what bugs me.
The worms in eco lifestyle reusing the rodent animation makes absolutely no sense to me. First of all, I don't know anyone who snuggles worms. Second, I swear in the trailer it doesn't even look like the sim is making contact with the actual creature. Would it have been too hard to make a new animation of a sim rubbing the worm's head with one finger or something? It sure shouldn't be.
I honestly could pull up so many examples from multiple packs, but it's not worth it. Instead of investing in modelers to make 40 different toilets, I say the budget should be geared to animators.
