My wife hates Portal. Hated the first, despises the second. It's the whiny robot voices, and the whooshing of the portals, and especially the gravity-defying leaps that make her sick.
So she wonders what there is to love about the series. I show her this, and she laughs, and while not settling in to play the thing, she at least can finally understand.
I play Portal like I used to play Wing Commander, or Command & Conquer. I endure the meat of the game, in this case puzzles, not to defeat them, from which I gain little satisfaction, but to see the cool/interesting/funny shit in between.
