Precisely. I can't understand why people so often seem to think that in order to praise one thing or person it is necessary to disparage other things or people. Time and time again it comes up around songs and singers. It's not quite the same as trying to work out some kind of order of merit, it's a sort of assumption that if this is good, that must be bad. Marmite and Vegemite for example
It's not unrelated to that other attitude you get where people react to some kind of criticism by pointing to the failings of some third party. "How dare you say that X is less than perfect. Just look at Y..." with X and Y being, for example America, or broccoli.
I'm surprised noone has mentioned "The Railway Children" in this thread.
And there's another film that I'm not surprised hasn't been mentioned, because it never got the hype - but it's great little film."A Swarm in May" And it's actually got quite a lot in common with Harry Potter, since it's set in a boarding school for children with an unusual talent, in this case for music, and a boy who has to do something he's scared to do but that needs doing.
