I wonder if it's a good idea to call it The Big Easy, since that title has already been used for a New Orleans-based TV crime drama that ran for two years on USA in the late '90s, based on the '86 film of the same name.
Even if it hadn't been used before, the name is too generic, and doesn't communicate supernatural elements. But some play on The Big Easy would work...The Big Eerie?..nah, too much confusion with Erie as a place name...The Big Queasy? not quite the right connotation there. Boo Orleans would work if it were on Nickelodeon...
