That was exciting!

I liked how it showed tension within the Silurian society, rather than paint them all with one massive big green brush. And the balance with a human going wrong was also good. I really liked the science-guy.

And Rory! Dead? Really? That was quite a shock. I wonder whether it will stick, or whether some weird time-thingummy will bring him back. Perhaps that is what causes the crack? The Tardis exploding in an attempt to cross time lines and bring Rory back once Amy realises what she has forgotten? I wonder whether the ring is in the box, as the box is clearly still there.

And now I think about it it seems obvious that the reason why Amy cannot remember the Daleks and Cybermen must be because they have come too close to a rift, too. Somehow. Hmmm.

Thoughts?
