Yeah, I watched the premiere tonight, too. I was actually pleasantly surprised by how good it was. I wasn't expecting too much, since the premise was a little weak, but the writing made up for it.
I thought most of the acting was good, although some of the smaller parts weren't that great, and I thought there were times that the mother didn't quite act up to the moment.
Overall, I think it has some real potential, and I'm already looking forward to next week's ep. I noticed it was very Lost-esque, which makes me happy.
