The Scariest episode in my opinion is Midnight. I always found it more scary when you can't see the monster, and also the whole "Small group isolated and trapped" always makes me shiver. While repeating every word is not normally scary, I found it quite creepy in this episode. It also helps that I think that Murray Gold's score for this episode, he was of the creepiest he has done for this show.
That's it for the 31 Days Of Wholloween Companion Blog Post. I hope you enjoyed them. :-) I would like to thank Rachel for hosting this really fun Photo challenge.
