I decided to put up a review of this film after purchasing it from Amazon, at just under 7.00GBP.
To be honest, their cannot be many people who have not seen the movie before, although, perhaps like me, it has been quite a while. DVD special features (or lack of them) don't really concern me, and this review concentrates on the film.
Basically, Eastwood is hung in error by a posse in search of a murdering cattle rustler. Eastwood is found by a passing Marshal, while still alive. After being cleared, he takes a position as a Marshal himself. While "vengeance" is to some degree in the film, Cooper (Eastwood's character) does not actively go in search if this for most of the film.
Anyway, to the main question: satisfaction and value for money. At around the price I paid, 7.00GBP, the film is worth every penny, although I would be less inclined to pay more. For the viewer, the film is a very good watch indeed, save perhaps for the conclusion of the story, which, although told clearly, may leave some wanting more. Of course, judging it by more modern "revenge" movies may be a factor, but in it's genre, it certainly delivers.
