I love that guys movies, it’s weird as well but if you think about it his movies have very simple, traditional plots but just with a very weird twist.
For instance Signs is the story of a former preacher disallusioned with god and the church he becomes a regular farmer. In times of trouble his brother moves in and the two live on the farm with the preachers two children. Through adversity they come through, with their faith renewed and a closer family. The preacher returns to the church and we all live happily ever after…now add the twist as an alien invasion and you’ll see what I mean.
How about Sixth Sense…A young troubled boy who has problems connecting with people and being bullied at school. A counsellor helps him become a better person, adjusted to his surrondings and eventually popular at school and closer to his mother. Now add the twist of seeing dead people and you’ll see what I mean.
