some people on this messageboard seemed to enjoy this movie, though i can't imagine why.
it's hardly cinematic; it tells its story in a very heavy-handed fashion. i couldn't believe my eyes at the sight of the first scenes that had dialog; not only were the lines really corny, but throughout the scene, each of the two actors (james coburn and virginia madsen) got a close up while delivering his line! even for utterances as negligible as "okay"! i didn't think such disregard for storytelling technique is even possible anymore, but there it is.
the movie did get a little better as it went along, thankfully, and delivered various flashbacks detailing coburn's history (on film) and the gun's owners' (on video) to liven things up a little. but the movie doesn't know how to deliver any insight into american gun culture. coburn's voice-over is comprised of his embarassing letters to his dead daughter(!). finally, a surprise ending negates most of the movie and leaves you with close to nothing.
as for coburn's performance... you won't hear me say a bad word about him, but i just can't praise his performance in "american gun". i assume his oscar for "affliction" was well-deserved (i haven't seen the film), but i don't see any awards (or nominations) for this one.
the storytelling style can best be described as "naïve", and that's the kind of movie-goer you have to be to enjoy the movie.
