Don't understand all the guff about Tapping's accent. I couldn't watch the first half, but listened to it while I was working. I assumed that the good Doctor was being played by an English woman, albeit one who's lived in America for quite some time, and lost some of her British accent/picked up a slight American accent. It wasn't 'til the second half that I saw it was Amanda Tapping.
All in all, the show was good, albeit a bit derivative. If they can continue to deliver this level of quality, I'll continue to watch.
