Heh. My brother and I grew up watching James Bond movies. And obviously, these movies are entertainment and fantasy, not documentary and physics lectures. We all knew that. We all accepted that. But one day my bother went to see a James Bond movie, and he came home positively spitting nails.
It was the the movie where there is a chase scene on skis, so Bond skis down a mountain, and the bottom of the mountain delivers him to the roof of a chalet, and he skis down the roof, and off the edge, and lands on a picnic table, and skis across the table and then keeps on going. And when I say "picnic table", I don't mean a deserted, snow-covered table. The table was laid with a table-cloth and a picnic and people sitting all around. (I don't recall if Bond came off of it with a dinner roll stuffed in his mouth, like a Loony-Toons character).
Anyway. The problem was that my bother skied. And he knew, from painful, first-hand experience, that if you are skiing down a mountain, and you hit just the tiniest bare spot--just the tiniest patch of dirt or rock--it feels like your ski has been grabbed by a bear trap, and you're lucky if you don't tumble right there. Skiing across a picnic table isn't a skill, or a stunt--it's just flat impossible.
Bond movies are unrealistic, yes, but this one was unrealistic in a way that he couldn't accept. And it killed the movie for him.
