I have to agree - with everyone. I did think that the BBC version was better, but that is probably because I saw it first and loved the characters.
It makes sense that the American ghosts would have to be different - historically. The more I watch, they are both really good. It is a show that I hope can continue for a long time. Both versions. There is not a lot of light hearted TV that is currently airing. I find myself watching YouTube and reruns of old favorites in my downtime. But I really enjoy this show.
