I agree about music - it is getting worse day by day... but as DS said - repetitive catchy tunes with no meaning have been in the industry for ages.
Moves are the same - when you were in 90s you've seen mostly good ones that were made in 80s and 70s and skipped all the crap. Now it is CGI, back then they used explosions... but good movies still exist.
It seems that you've really haven't been playing new games - this is one of branches of entertainment that is getting better and better - i agree that there are some bad games, and inide glorification is bullshit - but generally it is getting better and better.
90s weren't so great - you've just seen only good parts of them.
