The opposite of the previous award, here's the Worst Cliffhanger:
MERLIN THE TEARS OF UTHER PENDRAGON PART 1
So, 3 minutes from the end of Merlin series 3's opening episode, and Merlin has been stung by a scorpion and left to die. However, he calls out and the Great Dragon rescues him. End of episode. Credit to the Merlin team, because the finale's cliffhanger was a cracker. Tomorrow, Best Two Parter.
