I purchased this DVD because I remember enjoying the movie on it's television broadcast in the late '70's. I guess I was younger and my tastes are more discerning now. First, the transfer was terrible, with much of the colors faded, washed out or "burnt" out. Also, images were usually soft, sometimes out of focus. I am sure this was the fault of the transfer process, not the filmmakers. This is the 2010 Echo Bridge Home Entertainment version and it is really a poor transfer. The DVD looks like a bootleg transfer from a bootleg VHS copy. The front of the package states WIDESCREEN across the bottom, but it is neither letter boxed nor a correct ratio as often the images from the left side of the screen are clearly clipped off.
From a film critique point of view, the acting is stiff, and either wooden or over the top, depending on the actor in any given scene. The camera work may have been OK, the transfer kills any hope of seeing good photography. I think the story is very good and could have been so much better. This is one of the few times I would like to see a re-make, as I think the story had much potential. The final "Race Against Crooked Sky" should have been an edge of the seat nail biter. It wasn't. The characters motivations lack depth or commitment. You feel as if the characters are motivated only because that is what the script told them to do or say. Richard Boone is somewhat entertaining, doing a somewhat of a "Rooster Cogburn" type character.
Last note, this particular transfer is the edited version, definitely PG, as the brief nudity discussed in other reviews is not present in this transfer.
