I think you've missed the point.
The great thing about Chalet Girl is that it doesn't follow the easy cliches of similar films. It doesn't make her chalet colleague a bitch on legs who makes her life a living hell or a fairly typical adversary. It doesn't make the family she works for Dickensian in their attitude, just mildly horrible. Plus it has a seem of cynicism running through it which fights against the assumptions of hiw romance is supposed to be, helped by a storming performance from Felicity Jones. It is what it is, but at least it does it with some appreciation for the limits of the genre its within and does its best to work against them.
