That might indeed be the core problem yes, sims 4 wanting to be too happy and pleasing everyone. It lacks drama, it won't let sims do anything mean or naughty on their own. And it's all too easy, no challenge.
While the game is made to be suited for 12 year olds, it often feels like it was targeted for that to be the main audience. Most people who play this are adults, so I think they should aim for that while not making it too unsuitable for teens, they could play it if they want but should not be catered to as the main audience.
Not having individualism would only hurt teens anyways, when all sims act the same and lack personal identity. Bad example.
