Why does everyone seem to hate this episode!?! I thought it was really good, but I can understand why some people didn't like it. But do you really have to say how much you hated it on every thread? You have to admit that there were good parts of the episode, even if you didn't like the idea of a musical or a whole episode being a story. There was more to it than that, and it was showing the emotions Walter felt but in an entertaining way. 5.6 million isn't that bad, and I'm glad there were at least that many viewers. I thought there were great performances by all the actors, and it was really funny. If you didn't like it, that's fine, but is it really necessary to continuously trash it?
As for the ratings, I don't think the show will be hurt. Maybe first-time viewers will think it's a kind of odd show and won't want to watch it again, but as for people who have been following it for a while, I'm sure they'll tune in next week. Plus, first-time viewers might have liked it, and next week's episode looks really good. I think the ratings will go back to normal.
