I have a feeling that some would dislike it, but I just saw a very good recent low budget western called Cowboys & Indians (2011), the work of Aaron and Tyler Burk.
We see some guys in the desert. They briefly express fear of the local Indians. They dig. They find gold! Gold! They're rich! Then the Indians kill them. And it happens about that fast.
I don't think the Indian nation portrayed in the movie ever existed.
Seemed to be filmed on digital video.
Available for instant viewing on Netflix.
We see a pioneer woman in a sun bonnet sitting at the bar in a saloon with a filthy prospector hitting on her.
"Please! Sir! I'd like to be left alone!"
