Our group ran this for 5e but the comments are the same.

Loved it. Its definitely a one, maybe two shot adventure, wont take long to run. Some might be turned off by the lack of a hollywood ending wrap up but our group really liked the amibguity and i ended up using it to start something new and tie in to the setting ive made. Great stuff, very atmospheric, haunted farmhouse seems straightforward and it is until you get to the basements. Lots of secret rooms and great crawling. MORE PLEASE
