the ending
Okay, I can accept the ending but it did come out of nowhere.
Here's a smart old soldier and he's riding double-crossed on horses into a possible ambush? He knew there would be a scout party up ahead that crossed the fog. He did say something about "he should have left earlier" but still, I'd like to have seen something smarter because Valdez knew what he was doing.
