It hits the big four as far as I'm concerned
1) Family Friendly
2) Expansive Environments
3) Nostalgia
4) Merch Potential
Seems like a logical choice
You all are missing the biggest thing, the ability to be able to turn into theme park attractions. Hunger games is a huge franchise doesn't mean its easy to create rides based off it. Same thing with Twilight and to some degree though everyone is going to attack me on it Lord of the Rings. it will make a beautiful area but when it comes down to rides and shows, it doesn't lend itself well. However, it would bring people in the park.
