I think the main complaint is that the percentage of the kits dedicated to specialty parts limits their usefulness for free-form play. Sets of the 80's had fewer block types, which forced Lego to be more creative in how the sets were put together, which subsequently allowed more freedom in using the blocks for other designs. The sets my kids are playing with look much more "realistic" to what the set is trying to model, but very difficult to build something entirely different, such as building a house from a car kit.

I understand the complain, but from observing my kids play with LEGO I don't agree with it at all.
The specialty parts from every kit inspire a lot of new builds with their growing part collection.

I guess I just don't see this with my kids at all. Every small set we buy or that someone gifts them grows the range of things they can build. They remember every single different part and will go searching for it in the bins because they want to put it to use.
