This episode is just iconic.

It pulls together a bunch of plot threads from throughout the season as The Doctor is cornered by all the enemies he has faced up to now. River gets up to the usual antics, Rory's reunion with The Doctor and Amy is bittersweet as the Doctor remembers him but Amy has no idea who he is.

Of course, this episode has the legendary pandorica speech, one of the most memorable moments in the entire show, and Matt Smith does a fantastic performance here
