What a technically sound film...
I was awe-stricken at the technical proficiency of the shootouts in this film.
Quigley's Sharps was such a beautiful masterpiece, it was a character all its own, which really helped set this film apart from just any other western.
What I liked most was how well Selleck sold his handling of the hardware. The aiming, the reloading, the double-triggers -- it was a masterfully composed film that really seemed to pay great respects to gunfighter culture.
As some others said, it's a shame that there weren't sequels for this film. I really feel that -- after going back over and re-watching some of Selleck's old films -- he was really shortchanged a bigger career in Hollywood. I imagine had he been born a few decades earlier he would have been an even bigger star.
