The message the music the wall. The wall is a movie about the life of man (syd barret and roger waters) and about how he ruins his life and how the world helps him they show facts like the over protective mother, strict teachers, cheating girlfriend and drugs did to him.
It is truly worth watching and not to mention the amazing music. Its surprising that how a movie so good was actualy sort of an accident (a movie wasnt the original plan) Flyod at first wanted to make a concert into the movie which is pretty good to watch as well but finally ended up making a movie which was a massive achievement.....
If u want to get like a good picture of the movie then just listen to another brick in the wall all the parts, comfortably numb and mother and bob geldof did a brilliant job playing pink.
