After the second episode, all the content is an "ODE" to the Vegan Diet and its benefits, for a lot of minutes you can forget the "Twin Experiment" and the characters of the experiment. Personally I guess this documentary is one piece more of the vegan campaign in the american's diet people. I think that wasn't a clean fight between omnivore and vegan diets, but I only just a "mr. nobody! from the third world.
