Netherworld has been lying to you—it's really two haunted houses: Banshee and the Hive. Both are marked by attention to detail, just like your favorite serial killer. The costumes and makeup are so real, so carefully put together, you'll have the unique experience of being impressed while you wet yourself. Watch out for the Hall of Mirrors—you may not be able to walk straight after.
