Doctor Who - Season 5, Episode 01: The Eleventh Hour
Trailer
Amelia Pond finds a crashed TARDIS in front of her house and invites newly produced Eleventh Doctor to examine a crack in her bedroom wall. TARDIS has Doctor, Amy and few other people inside it who now have to fight against the evil villains.
The Eleventh Hour is fraught in a way Doctor Who hasn't been since Rose. Most of the time, you don't notice it - because the episode almost just about is, in fact, perfect.
