At first I was, after all the negative comments, also very skeptical. After playing now 2 days, I have to say this is the best ever Sims what it was.
All the interactions that the new Sims can run now are just great. Thus it happened, for example, that my Simin very excited about their food was and it still photographed smooth! Another time took my Simin a bath and her husband did not want to eat alone. So this took his food and ate with the bathroom to be able to converse so.
Even the CAS system is really great. It has never been so easy to create a Sim exactly as they wish.
What has also become really handy, you can re-clothe the dresser all Sims without any einzelnd to send to the bureau.
I can only advise every game to let sink in and to play an open mind.
