It's a bit difficult to make an argument for giving this album anything less than 5 stars, unless you're a very dedicated Pink Floyd hater. Or maybe if you were born in this millennium I suppose.
At the same time, it feels wrong to give my 5th favourite Floyd album 5 stars. It's a fantastic production and has masterful production and storytelling. Very cinematic and ambitious. But it really demands the listener to be in the right mood to get through the whole thing, and is hard to listen to casually, apart from the big hitters. And if I'm in such a depressed and nihilistic mood, I'd usually rather put on Animals or Wish You Were Here. If I want the concept-heavy, meaning-of-life Pink Floyd, I'd rather Dark Side. If I want something fun and spacey, it's Meddle.
I'd also argue that you could probably just listen to In The Flesh?, Another Brick in the Wall 1-3, Hey You, Comfortably Numb, In the Flesh, and Run Like Hell, and still get a pretty complete picture of what the concept is. So I kind of agree with those who say it's bloated and indulgent. But that's also kind of the point!
I also have to deduct points for the ironicly poor grammar on Another Brick pt.2, so I'm landing on 4 stars.
