Except for the finale, season 7 sucked. Not Matt Smith's fault, it's Steve Moffatt's fault. Once Russell Davies left, the storylines took a dive in quality.
the more I think of it, the more I like the idea of a James Earl Jones sort of Dr. -- it would certainly give the show gravitas
Can't see that dignified an actor kicking a Dalek's ass, though. Maybe rethink this.
