He's made some amazing films over the years and definitely knows his stuff.
That said he's clearly more of a 70s era guy and I still think he's pretty wrong about this one. Its also kind of interesting to hear him gush about stuff like Top Gun while saying stuff like this.
It comes across less as he dislikes all eighties movies but more that he doesn’t like the commercial aspect of so many of the films from that era.
To a degree I understand what he’s saying. Films lost their edge to become more crowd pleasing. The same thing is kind of happening now only for different reasons (people are so much more hyper sensitive so studios largely avoid risky films).
