Why was ABC so quick to say "not" to Emily's Reasons Why Not, the heavily hyped and Heather Graham-fronted comedy that it pulled after only a single low-rated airing? Network entertainment president Stephen McPherson explained to reporters on Saturday: "Once we saw it was not launching, we felt like unfortunately it was not going to get better and we had to make a change." Still, you don't diss Rollergirl like that. You just don't.
