Oddeus: […] Has Hollywood forgotten how to make good movies?
Well, they would be quick to point out their box-office receipts. Basically, as I tell my octogenarian mother, movies these days are made for a different (younger) demographic. People who haven't seen any movie (let alone a film) made in a year beginning with a one.
That said, there are classics to watch; they have become classics because they have survived over years to be worth re-watching, for multiple reasons. There was a golden age of science fiction in the fifties, then again some in each of the subsequent decades, but —— inevitably —— Hollywood created a surfeit that ended with cash-in crap.
Classic films from iconic auteurs, like
A Clockwork Orange from Stanley Kubrick,
Alien and
Blade Runner from Ridley Scott, even
The Day the Earth Stood Still (though I prefer the eighties remake, except for Jaden Smith): and
Forbidden Planet are good, from the 50s, even though science has progressed far in the years since.
edit: Jaden Smith
