Rate "Before The Flood"

Episode 4 is already upon us, and it's the conclusion to last week's "Under The Lake." Here's your official brief:

"Doctor. Hello. Can I just say: huge fan."

In the eerie remains of a town that never was, something is stalking the Doctor and his friends. A desperate battle for survival is underway, but this time our heroes already know which of them is going to lose. With the past and the future hanging in the balance, the Doctor is breaking the rules to win the day. Can anything stop the Fisher King? And more importantly, who composed Beethoven’s 5th?

I must say, some provocative questions where introduced at the conclusion of last week's episode, so I certainly plan to tune in Saturday. Just a reminder for North American Wrinklies: this thread comes with no spoiler warnings. If you visit this thread before the episode airs on this side of the pond, and you read something that ruins the story for you, you have only yourself to blame. This thread will remain locked until UK transmission of the episode on Saturday, so once it's open, please feel free to vote and post your thoughts on the story.

I think one had a sort of hurried up conclusion. Not as good as part 1 in my opinion, but still quality. I give this a 3.
