I'm not sure why it's rated so low. It's a entertaining show, similar to A Haunting, I recommend it to fans of A Haunting.
The story, the acting, none of it's bad. I personally think it's great that we have shows like these on TV.
I think the show has a low rating simply because people do not believe in the super natural and don't think it's scientific enough to be featured on the Animal Planet channel.
I find it very interesting that animals may be sensitive to the paranormal, but there are people who obviously don't believe in such things and think the shows entirely stupid.
As some one who both likes animals, and the paranormal, I'd say that I'm in the target audience here and I enjoy this show fairly much. Yet, people will judge, even if they don't believe in such things.
At the least, hopefully people who have a interest in such things can be open minded and enjoy this program.
