I guess so. The producers went for authenticity 'n captured it nicely.
But ya gotta go with the premise that Liv is 'ordinary' looking. She tries to be. Too many in the audience would've seen her in other stuff though. So as the film progresses and she becomes a dynamically strong-willed personna, we already predicted it. Because she's too good-looking in the classic sense.
Which makes Zandy's antics sorta unrealistic... When you're married to a 'goddess', living in a ruggedly remote landscape, you'd tend to fawn over her a bit. -Not run-around all independent and uninterested.
It's a chick Western. Lotsa emotion leading-to a satisfying ending. Hackman's and Ullman's performances are technically superb.
