7th Heaven is quite a hit for them now, and they are hoping to appeal to a very similar audience with our show; skewed slightly older I guess, since it's a 9:00 to 10:00 show.
My guess is that if they now choose to change of director for every other film, it's just because you can't really change the formula, you can merely try to film it your way.
We take art, and I love all that. But I also like science for some reason. I just like finding out why things happen.
