What a fantastic piece of TV! I just don't know how to put it into words, but it was just brilliant. It looked like a movie and had a wonderful air of mystery about it. The aliens are amazingly scary and that bathroom scene will go down in history as one of Who's scariest ever scenes.
Can't wait to see what happens next week. I have no idea what is going to happen. It's not your typical "ahhh we're surrounded by baddies" cliffhanger: it's more of a "we're not sure what's going on" cliffhanger (in a good way!). ha ha!
