10. The Angels Take Manhatten
If you can cast your mind back all the way to last year, you might remember this one. While the episode itself left something to be desired, before broadcast anticipation was through the roof. For a start it was the last episode for the longest serving (full time) NewWho companion Amy Pond, and her husband Rory Williams, so it was with this knowledge in mind that viewers watched this trailer. What makes the trailer great then, is that it largely consists of a couple of shots from the episode, with a voice over from the Doctor reminding us just how effective the Angels have been as villains in the past. Of course it would be silly for the trailer to show too much of what is going to happen with Amy and Rory in the trailer, but the reminder of how terrible the Angels can be sent chills down the spine, because we all knew it could only end one way. Add to this the creepy tease of the new 'Baby Angels' or the Cherubs, the return of River Song, and the vague image of two people falling from the roof of a building, and the episode couldn't come soon enough.
