I once forced some pals on a skiing holiday to spend an afternoon off the slopes watching Chalet Girl. Suffice it to say, I have a high tolerance for lowbrow ski films. So if saccharine tales about plucky Alpine underdogs really aren’t your thing you might want to give my views a miss — as you might Eddie the Eagle, a biopic so drenched in cheerful clichés about the British class system, the power of perseverance and cheap slapstick laughs, it is a kind of Downton Abbey on skis.
