Just finished reading this!
First and foremost, the script is very funny. The dialogue is humourous, the situations that arise too and there's some good physical comedy in here too.
When the first murder happens, and everyone's scrambling and around accusing each other, the screenplay is arguably at its most fun. It almost felt like an edgy Scooby-Doo episode (in the best possible way) where the killer feels like it could be anyone.
Joe and Amelia to me have the best dynamic and are the most interesting pair of characters. The others don't quite feel as fleshed out as they probably could be to feel memorable. In fact there were times where I lost track of who was who because there were so many characters. Initially, however, the number of characters did add to the fun of it all. But I do think they could do with more depth.
The script is also very well paced, with it feeling like the events that occur have a natural progression to them for the most part.
It also does have a lot of intrigue and good weirdness to it, especially when they go down the tunnel and stumble upon the clearing and the room.
When we get closer to the end however, and the we're introduced to the man, it feels like we lose a lot of that intrigue. With him giving the characters a fetch quest, and them exploring the areas to fetch the items from (the tavern and the church) the script takes what felt like a much less interesting route. The showdown while entertaining enough, feels very easy and like not that much of a struggle for the characters.
It also felt like there was a part missing between Bruce and Claire going off holding hands and Steve and Mary finding them in the stable in hay. Not in a plot sense, because it is explained that they escaped one of the whispering figures and got there by wandering. It's just that them turning up there and then Steve and Mary running into them feels a little convenient.
