One thing, can we please not call the Ponds his in-laws? It's not as if that was a real wedding?
Why not? For time travelers who are used to various dimensions, they are used to doing things differently than everyone else. And they both believe they are married. What more does one need?
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.
My favorite "glitch" of this episode had to be a little boo-boo between scenes. Cyborg is coming through the town. Various characters are running around and they have Chakotay's tattoo drawn on. The Doctor is in the bar, getting his own. The barmaid has drawn only the one straight line above his eyebrow when the mini-explosion draws his attention.
The cyborg goes into the church. The Doctor rushes outside. The next time we get a good, clear shot of his face, he now has the full Chakotay.
So with the boom boom happening, he rushes back inside, has the barmaid carefully construct the rest of the tatt, then rushes back outside?
Or do we call this an oopsie?
