Too much of a good thing?

I enjoy Dancing With the Stars as much as the next person, but do we really need three evenings and 4 hours worth of it as the season premeire? I think they could have easily included everyone with their pre-show rehersals and bios and such neatly into two hours and cut the results show to 1/2 hour. All of the silly little commentaries can go, in my opinion. I like watching for the dancing. Show more of that! Also, don't go to commercial after every little thing. On the flip side, I was able to switch and catch most of the good parts of some other shows while I was waiting for the good stuff. My current favorites: Helio and Jane.
