I have found that movies with Timothy Spall or Maggie Smith in them are worth watching, and this movie has both of them. I also like Pauline Collins since her role way back in the Jurassic era playing in No Honestly.

I am not into the supernatural or ghost movies, so I don't know what is normal, but it seems like this script takes a few liberties by having the ghosts visible or not visible inconsistently as the story moves on, but the writers seems to realize that as one of the characters even comments on it. And overall it works so I overlooked it with ease.

Oh and did I mention Hugh Bonneville is in it, and very good, as you'd expect. The ending was rather predictable to me, but I write novels so perhaps that was why I foresaw the plot twists. I like that Tolly, the teenage the lad who is main character, shows some growth as a person due to his experiences. I don't expect to feel the urge to watch the movie again, but neither do I regret my time spent watching it.
