I feel like almost any new kit I look at is composed of big specially-molded bricks that would seem really odd and difficult to find a use for if they were deconstructed in a big box of bricks. Maybe I'm misremembering or am being too harsh on the newer kits, but I feel like the Lego sets I grew up with in the 80's and 90's were more reusable. I had the sense that every Lego kit I bought was also giving me cool new tools to build bigger/wilder spaceships and trucks, whereas these just look like a nice weekend project with no application thereafter.
All I'm seeing in these sets is mostly standard pieces, possibly with custom prints or stickers. The waterfall pieces might be entirely custom, but pretty much everything else is something you find in a lot of sets. Most things are made from small & reusable pieces like before, but there are just more kinds of bricks and they are assembled more creatively (especially in more expensive sets like the Creator Expert sets).

And stuff like that isn't new. I remember I had a "castle" set that had these wall-with-window pieces [1], which were kind of similar. You could still use them creatively. Also that waterfall set has a lot of pieces that would be good for building stuff like spaceships or planes.
