A huge hunk of movie, mammoth running time being a minor factor as such. A lot of people in, for the most part, a very tight space. (How in the hell are there a crew and equipment in there?) A lot being encapsulated (both nation-specific and extra-national). I often tend to separate the cinema that goes out to do art from the cinema that sets out to entertain. Sieranevada is actually all-you-can-eat entertainment.
