I've watched the first season and at least 10 episodes of the 2nd. I find it too melodramatic. Most of the time, it's not even scary.
I kinda like it. Yup I agree it's not scary. I think the people behind the show never intend it to be scary. They want it to be a dramatic kind of show.
This is similar to Eliza Dushku's show before Tru Calling. Never really a scary show but the drama of moving forward for spirits.
