I would have expected LEGO Ninjago to be as well. That's their own very distinct IP and the models that are included feature the best original LEGO models you can get. And that on a constant high level for several years now.

Funny that you mention LEGO Friends. In the German adult LEGO community lots of people don't understand LEGO's strategy with Friends and often shop owners on YT videos claim that they don't sell well enough for them.

But they seem to get sold more elsewhere than in the LEGO specific shops.
