Once he smashes his hotel room... Are schizoids violent? Smashing things up doesn't sound schizoid to me... Who knows?
He (Pink) lost his father in WWII and have dominant/overprotective mother. His mother make him to get married. There's one act where Pink's wife comes to home, goes topless, sits front of Pink, but Pink just want to watch tv. Sounds schizoid? Yes, right?

The whole Wall consept is about building Wall. Losing his father, dominant/overprodective mother, bad teachers... All them, they're just bricks for Wall. Pink keeps building Wall, but then he becomes a rockstar... Strangely enought there is not any info how it happens. At some point Pink is a rockstar. Anyway, under the pressure of the outer world Pink try keep his Wall up with using drugs, but Show must go on, so in the end there is The Trial. In The Trial Pink is judged as a guilty and Wall is torned down.
I tried not to spoil too much of this movie. Even if I'd told movie act by act, it won't be nothing. This is one of those movie that you need to see with your own eyes. Definently worth watching, even if you don't like Pink Floy music that much!
