(it's repeated tonight and next Saturday if anyone wants to watch it before they read this post)

So they finally did it... and set a dangerous precedent to appease a vocal minority of fans.

The topic of Timelord Gender-swapping between regenerations, which has been thrown around since about the sixth Doctor (if I recall), has been done on another Timelord instead.
It doesn't answer the "demands" for a female Doctor, but does now make it canon that a future Doctor can be female... and increase the calls for one. (and knowing marketing strategies, it will happen if ratings fall, just to spice things up a bit)

I was one who was opposed to the idea, and hate that it gained enough traction to end up becoming part of the Dr Who lore... because I think gender shouldn't be something that should change, as it would theoretically be very problematic in a "real world" sense.
Like, how does it work if one is pregnant and then regenerates into a male... does the baby get lost because there is now no womb for it to grow from? Or how about the peer pressure from other kids if a child or teen regenerates into the opposite gender? Or if there was a married couple and one changes gender, what if the other isn't willing to go gay?
It makes for an interesting plot device (like how it hid the identity of the villain in today's episode), but the ramification or reality of a one-off plot device is being ignored... mostly because it is not something they might have to deal with for a long time if Gallifrey remains lost.

I was really hoping it was a different Timelord who knew him, like the Rani... but no. It makes the whole passionate kiss seem even weirder.

You know, I can't remember if there was a Cyberman in last week's trailer, but when the doors closed to reveal the Cyberman eyes, that was a very well done lead up to a hint at what was about to come.

I laughed at the wifi and Ipad bit...
"you have Ipads in the afterlife?"
"we have Steve Jobs."
