I have not seen any other films in the Conjuring series. I wanted to go to the movies, I'm always in the mood for horror, so I decided on this. Not a bad choice.
David Sandberg does a really, really great job at building miniature set-pieces for the sake of visual horror. They don't ever add to the movie overall, but they are great little moments of fright (the scene when Linda sleeps alone for the first time is a highlight). I can't wait to see more from this guy.
