Context is everything in architecture. The rest of El Alto is unfinished, artless concrete and terracotta like the adjacent buildings in some of the photos, so it definitely lifts the neighbourhood, and the centre of nearby La Paz is dominated by concrete towers painted in similarly bright colours that just aren't as interesting. It's the graffiti of the architectural world, and sometimes the neighborhood feels more lively for it.
Not sure it would fit quite as easily in the historic centre of Sucre.
