I hate them. They don't even feel like real emotions, but a MMO buff system. Emotions are so unbalanced to being so happy all the time and traits don't really have an effect on them. If anything, the Sims 4 feels the most robotic to me in that all the Sims feel like the Sims 3 Into the Future Plumbot life states. Reactions being a hit and miss don't help matters too. Makes it hard to get emotionally attached to this generation of Sims. Sims act like they have short and long term memory loss. It is really depressing to watch sometimes.
