Doctor Who: Turn Left

What if Donna had never met the Doctor? What would the world have turned out like if all those alien enemies attacked the earth without the Doctor and Donna working together to stop them? What if the Doctor actually died because of Donna's absence?

Chaos, that's what would happen.

Luckily, there is another who has a unique perception of what's going on, inexplicably being shunted between parallel universes. Rose Tyler.

This was an exciting episode, as it had a good amount of edge-of-your-seat twists and turns. Russell T Davies tends to like hugely epic storylines, but ends them with a bit of a lame duck conclusion. As this is a setup for the big finale two-parter, I can only hope he doesn't ruin it by pulling the ending out of his butt with lots of technobabble deus ex machina nonsense. I live in hope.

Oh, and the "two words" ending was one of the most thrilling things I could've hoped for since the reveal of Rose in the first episode.
