This is a top-tier production in terms of acting, writing, directing, cinematography and the effort put into to accurately recreate 1915 south Texas. At first, I was a bit uncertain about Pierce Brosnan's seemingly self-conscious portrayal and iffy accent (he's an Irishman playing a Texan), but he quickly, comfortably settles in to his compelling character. The other actors are of the highest caliber, particularly the show's namesake played by Henry Garrett. The scenery is also beautifully shot. And the biggest surprise is the story itself, which becomes engrossing within 30 minutes into the pilot episode. I expect very, very good things from this show. Once again AMC proves they are serious about quality television, and I do hope viewers reward "The Son" because it entirely deserves your attention.
I should add a few people have noted some time-line discrepancies. These may exist, but they are completely unimportant. Some of the other reviews here seem to nitpick over ridiculous irrelevancies. I do not know how these people can enjoy television! We have to remember a product like this costs tremendous money for a television studio trying out an unproven new show without any guarantee of ratings, and we should at least be admiring of the effort put in.
