HHN is a real date, WTF? It's pretty dang expensive, most girls love scary stuff (it's an aphrodisiac), it's a great way to talk to someone because of the lines, you get to see their attitude, behavior and personality in various situations, they cling on to you a lot, there's time for meals to talk over like any other date, and it's a very long night so you get a super amount of time with this person you're getting to know. Better than "dinner and a movie" any day, especially considering during a movie you don't get to talk and dinner is forced and can be awkward.
Or at least I've had plenty of success with this date, but maybe that's just me lol
