It seems to have an American Horror theme based upon the website with the Wicked Witch of the West, Lizzie Borden, Bloody Mary, and American Gothic. Good theme, in my opinion, because some of these stories are pure American.
I grew up on Knott's Scary Farm which I've always considered to be the ultimate haunted theme park - but maybe Universal is going to give Knott's a run for their money.
And that teaser package is just awesome. Love it!!!
