I am a huge fan of the Virgil Cole and evert Hitch books. Anyone know how the Movie Appaloosa compares? I haven't watched it yet, and won't if it sucks!
I liked the movie, but it lacks the depth of the book, as adaptions tend to do. I think Viggo Mortensen did fantastic as Everett Hitch. I think the rest of the cast did well, but I didn't care for Renee Zellweger. I can't speak to the authenticity of the wardrobe but it looks good to me, same with the sets. I definitely think the movie's armorer did a solid job - guns aren't just chosen based off of looks; Everett carries an Open Top to accompany his 1866 Yellowboy (when he's not carrying the impressive looking 8 gauge mockup). Music was good. I liked it enough that I'm disappointed we didn't get more films in the series.
Having said that, the books are undeniably better. It's not a contest between the two.
