Mathematicians call Complex Analysis "The Disneyland of Mathematics". Everything you might want to be true is, and stuff you want seems to fall out of the air by magic. Numerical Linear Algebra is math's Exurban Sprawl. Everybody's problem falls into one of a few cookie-cutter categories, and nobody minds the sameness because the solutions we have are good enough and cheap enough. NLA is an amazing field if you think about it -- but you have to think about it.
