This is massive–supposed to be the largest airport in the world.  Oddly, however, it is not monumental, just big.  It is relatively easy to navigate given its size, but architecturally it is disappointing.  There is not the variation in spaces that is so memorable at Kansai Airport in a facility of similarly program.  This is just one big statement that keeps going on and on and on.  The skylights, which are proclaimed as a powerful feature, are actually quite subtle.
