I think it's a mistake to compare Le Corbusier-style "areas for living" with modern urbanised zones. The big issue there is that – sure – there's highrises, but no urbanisation. Usually because they are either lacking commercial space on ground floors or the density is too low, on aggregate, or the areas are too spaced out to support vibrant commercial centers. Look at stockholm, you have city, greenery, suburb, greenery, suburb. No urban connection, not enough density.

I've lived in areas like this myself, and I agree they're not nice. However, I have to think it's not only locality to city center that makes central areas good, it's also that they are self sustaining burrows. There's ample housing, parks, jobs, retail, restaurants, bars, etc.
