This is a very poorly constructed movie. I actually call it a mockumentary. Extremely loose with some but not all facts. Heavily slanted to the Left which in itself doesn't bother me. But honestly, the interspersed graphics and animations are just so poor; they just confirm the film is lightweight.
That the Academy has given it so many nominations is further evidence that the Academy has lost all credibility. And yet Mary Poppins was hardly acknowledged.
