Please explain without gobbledygook.
What does the above term mean? Do you mean to say that extensively showing the scenes of the heterosexual life of Ennis and Jack
does not enable straight viewers to more completely identify with the two characters? If not for that reason, then why would the screen writers add those scenes? Its just not a good enough explanation of the additions to say, that it "fleshes out the home life of the two characters", as McMurtry and Ossana have said.
OK, why "flesh them out" at all ? And why "flesh them out" in the fashion in which they were fleshed out?
If the screen writers are going to INVENT scenes wholesale, why not show more of Jacks philandering with Randall, or his undoubted cruising for sex in other area such as parks, bathrooms. Hey I'd like more of the scene with the Mexican hustler.
Why not show more of Jacks's cruising time when he was bullrider? We can go on and on.
There has to be a reason for the extensive additions over the screenplay, and emphasizing Jack's closeted sexuality does nothing to market the product because I doubt that most mainstream viewers would not be interested in those hypothetical scenes.
But they just loved Ennis's scenes with Alma and the girls. And Jack's scenes with Lureen.
