Literally ever new movie trailer be like: plays some generic or over-used, irrelevant pop-song, spoils the main parts of the film, and then comes the annoying drum:
I'd assume when they say "modern cinema" they mean movies coming out within a year or so of now, which likely discludes movies from before they were born. Rather than movies from the modern era.
I agree with the other points though. Trailers are interesting (though if I'm looking forward to something and know I'm going to consume it, I now avoid trailers and advertising for that)
