I think the main problem people have with this pack (just like they had with Batuu and Eco Living) is the fact that there are SO MANY highly requested featured that haven't been added yet, but have been requested for a REALLY LONG TIME and have been teasered or mentioned in surveys quite a few times. For example: hotels, bands, better babies, Generations, fairies, werewolves, more gameplay for kids/teens (high school), malls, and much more.
But instead of getting those we got lots of packs no one really asked for (I know, there are ALWAYS people who write they have ALWAYS wished for pack XY, but most of us didn't ask for interior design, Eco Living or Batuu, let's face it)
I think they really need to meet those longterm requests and then people won't be so negative anymore.
Another factor is that this time lot of people thought it would be active school, bands or fairies or werewolves, as there were tweets and hints that pointed into that direction. Similar to back then when we got Eco Living, when everybody thought it was going to be Farming because of this one fake leak and it got a huge backlash because of that.
So they really need to meet our longterm requests now. Then packs like this will be a welcome addon and not as badly received.
