Two good things about this episode:
1) The conversation between Arthur and Merlin about destiny.
2) Gwen's reaction shots during the failed wedding ceremony.
Everything else: so much fail. Show, why do you hate women so much?
Next week's episode has potential, but after this week I'm not holding my breath. Who wants to make a bet on Gwen's brother surviving the length of the episode? No one? Don't blame you...
