It's obviously a little over-inflated and heavy-handed: I'm pretty sure I didn't need so many thuddingly literal visual versions of the analogies already manifest in the songs: "schools are like a factory, man!" On the other hand, not only is it executed with a kind of thunderous conviction, the actual music is so well produced that it's not at all a chore to experience, even if you do have to zone out after the first quarter-hour minutes of "what if fascism but in Britain!!!11". Visuals that, after a while, suggest a creepy kind of curiosity about them.
A troubled rock star descends into madness in the midst of his physical and social isolation from everyone.
