That's ridiculous!
I'm only suggesting that sometimes we can work outside the strict-utility box. Not everything has to be a high-order intellectual/aesthetic experience. Our subway system is used by people of all stripes, of all backgrounds, it should play to them occasionally as well.
However, maybe it's less a matter of altering the way the subway looks, than of altering how we frame the way it looks? Case in point (and oddly unmentioned/overlooked through this phase of discussion): the Spacing subway buttons. As a popular success, they've done more to redeem the so-called "strict-utility box" than any drastic alterations away from strict utility can. Believe it or not, they've "popularized" the so-called bathroom-tile banality, to the point where vilifying it seems increasingly a step backward into yesteryear, somehow.
If that building was falling apart and in terrible need of a renovation, and there were 12 others much the same beside it, I'd entertain the idea of changing the envelope and seeing how it could be changed or updated.
Considering the edifice in question, your entertaining the idea of changing the envelope would be vetoed on the spot. And if there were 12 others much the same beside it--presumably all by Parkin, if you're trying to draw a subway analogy (and almost like a mind-blowing Toronto answer to this)--it'd still be deemed highly questionable. Maybe not in 1988 (when Modern was "out", Postmodern was "in"), but absolutely in 2008...
