I think the movie had extra dramatic effect to it, but the doors are not nailed shut. Still, I would not stay there. The tour is very in-depth specially if you ad the behind the scene tour.
Doors aren't nailed shut, but there are some doors that are unusable because she'd decide to change a room or add something new, just like there are staircases to nowhere.
I saw no nailed doors on the entire tour.
Basically everything about the movie's storyline was false except the fact that there was a Mrs. Winchester, her niece and the house. Her niece didn't have a child; there was no psychiatrist.
