The stuff they were doing with Sandoval in season 4 is what got me genuinely hooked on the show again as opposed to just watching it out of inertia.I came to feel sorry for Von Flores, because he was the only cast member to stick with the show for all five seasons as it got progressively worse, and he was such a talented and charismatic actor that he deserved to be in a much better show. I kept hoping for his sake that he'd depart for greener pastures along with everyone else, but he never did.
Then they seemed to turn him into a one-note villain in what I saw of season 5, so so much for that.
