Not sure if I liked that episode. It seemed to have more things wrong with it than right. We knew it was going to go either way, but sadly it veered to the bad side. Didn't like the way Martha was misused, or how she overreacted to the dying Hath (couldn't it of swam, being half fish an all?). The thing that was good about the episode seemed to be Donna (who is getting better as the episodes come along) and the Doctor, but even he looked bored through most of it.
I didn't like how it ended, I wasn't a fan of Jenny.
Oh well, another week, another Doctor Who episode to look forward to.
