... (and I was slightly reminded of Crichton when Isaac demanded what was going on after Jex put a gun to Amy's head).
Yep, Browder is the master of puzzled but intimidating.
I loved this one. Much, much more meat to it than the dinosaur droppings they had on last week. Jex's self-sacrifice was too predictable, and I kept hoping for a clever twist to get out of that, but turning the Cyborg into a sort of 19th century RoboCop redeemed the story. Really, the episode was about the Gunslinger's journey and not that of Jex.
I noticed a few fun production glitches. One scene has what I think was Alcazaba of Almerķa visible in the background. That's a castle built by Moors in the 10th century. A neat setting in its own right for Doctor Who,
but one that shouldn't be visible from anywhere in North America. Then, in a neighboring shot, the desert trail the Doctor was riding along was blurred out ... presumably to hide the tracks of off-road bikes or something.
