The Movie: The Strangers was highly rated, but I found it rather dull. I like movies with gore and this movie had sadly little. Was it scary? Yes and no. No in the sense that I slept perfectly well last night, and yes in the "realism" sense. It was extremely realistic.
I don't want to discourage anyone from seeing it, because a lot of people would really like it. It just wasn't my type of movie. I don't regret watching it, but I wouldn't watch it again.
Hope that helps.
