I remember seeing Rocky IV at the movie theatre...
Completely packed,the audience screaming and cheering like they were at a real us-vs-them fight.The music intensified everything.It was just great!
Then at the lobby the Rocky 4 movie poster book was completely sold out.Then when I went to a store shortly after,The Survivor song Burning Heart was blasting.
I think the young people watching Rocky IV on Netflix for the first time then criticizing it do not get how this movie was perfect for that time.An exciting blockbuster.
