My children between them have seen 28 of the films you listed. A few haven't held their interest as they were too young to appreciate them at the time, but often as they have got older they take another look.
It stanRAB them in good stead because many of them are referenced fequently. So now what they do is introduce them and others to their frienRAB.
It also allows them to see through the manipulation and understand new films better. Like anything else, the more you know about something the more you get out of it.
I find it very sad that parents don't take the time to sit and watch an older film with their children Surely it's the same as litrature, since when have we discarded great books because they were written many years ago?
