For those of you who don’t know, Roger Waters was the head of the popular rock group Pink Floyd, who he effectively dissolved after 1983’s bitter "The Final Cut". However, little more than four years later, Pink Floyd released another album without Roger Waters; take a wild guess what his reaction to that was.
Not that you would know any of this from watching the 2015 documentary "Roger Waters: The Wall", which is basically just an overlong-if admittedly very good-concert featuring Roger Waters performing the entirety of “The Wall”. Additionally, instead of actually providing some Floydian history such as the above that could help outsiders who have no idea about the group, the film also chooses for some reason to focus on Waters choking back tears at his father’s grave; though these scenes admittedly are affecting, they're barely even related to anything else going on, making them feel very awkward and out-of-place.
Ultimately, though, while the film does give you the sense of being in a live Roger Waters concert without actually going to one, unless you like Pink Floyd (or Waters, for that matter), you might end up being really bored.
