A nice fun adventure! Ran it for a halloween one shot and we had a lot of fun. We played it without using the premade characters and we didn't have any problems (except that i had to lower the DC of the investigation checks as none of my players had enough Int).
It really solved the question of "how do you do a one shot inspired on this classic show in a fantasy world with real ghosts?" and nailed it with its formula of having Scary encounters in one hand and Very Scary encounters in the other.
The only thing I would like to see improved are the maps, as there isn't a size stated to import them to VTT. And I had to crop and manually scale them. And sadly, the maps are black and white.
