So we start with the premise of this is the National Anthem is based on a British tune and is all about war and conflict- which I suppose is true, however, thinking this audaciously as to being appointed the arbiters of culture based on your personal views, and only considering an infinitesimal amount of locations, and then only a tiny fraction of that particular locations population, and you get this mess of a movie.
These two seem talented enough on their own, and together maybe even more so, but there's not a thing about the increasingly limited scope used for their purview that remotely lends itself to something close to representative of the country we share. So many are completely removed from the equation that it leaves much to the imagination as to what they thought would be the end result.
Of course this won awards at a film festival; as of late the festivals all seem to be in competition as to who can out signal each other with their back-patting choices that are low on substance but give the award givers a big helping of 'the feels' for being edgy and virtuous. Even if this particular film weren't so full of itself trying to reinvent the wheel, and instead came from a place of creativity that sought to simply write a great song based on lives lived, it's such a small vocal presence used for the sample that this would be a song for a select few, at best.
I expected a lot more than what I saw, and felt largely underwhelmed as a result. Very meta given the current environment and not very open to the possibilities.
