True, it wasn't the best episode in the world, but Series 3 in the long run was the best yet in my opinion.
I find it kinda melodramtic that someone can say they have SERIOUS doubts about the future of the showm just because of one bad episode, there were probably worse episodes/serials than that in the classic series (especially later on, where the writing just became inexperienced twaddle).
I honestly don't see how the show is going down hill after one bad episode, there were plot holes, yes. But as "Teh Ronn" said, I'm not gonna lose sleep over it, the only serious problem I had was the regeneration (I just don't think Time Lords have the choice in Regenerating or not).
Over all, the series is getting better, nothing's perfect, and if you disliked it THAT much, then write in and tell them yourself, instead of just moping on about it.
