GB and Beetlejuice were franchises that were deeply rooted in USF's history and they just happen to be humorous.
Stranger Things is too big of a property with horror elements to let slip by...also it can legitimately frightening at times
Horror Nights is certainly less intense than it used to be...but I don't blame that on creative or IP choices, I blame it on size
Also, the term family friendly is kind of silly to me as I went through ScreamHouse with my family and we all quite enjoyed it lol
