Watching "Under the Lake", I was really impressed with the creepiness of the episode. I mean the ghosts are really creepy with their eye all blacked out. You know this is 2 episodes in a row now that I have been creeped out over eyeballs. You had the the hand mines with their eyeballs on their hands and now these ghosts with no eyes. With that being said, this first episode is a great mixture of what makes Dr Who great. You have a fantastic mystery, paranormal activity, science fiction and it's all mixed under a lake.
