I’m responding to your assertion with observations. The Bad NEws Bears was about the Walter Matthau character. E.T. was not about the adult characters at all. It’s told entirely from a child’s point of view.
How about L’Argent de Poche?
Very popular.
Another question. You call ET a fantasy, but call it science fiction in 6.
Those aren’t the same thing. Which is it?
Also, as far as your definition of movie about children, you maybe should define it more. It seems that there was only one ever made, which was ET.
You’ll need to cite other movies that qualify.
Were any even made that qualify under your idiosyncratic criteria in the 15-20 year window you ask about?
If so, what were they?
