How Scary Is Obsession? Is There Much Gore?

Actually, I’m planning to watch this movie with my wife, as I usually don’t prefer watching movies alone in the theatre, especially after getting married and now that I’m over 30. My wife usually can’t stand gore and bloody scenes, but she can watch horror and supernatural elements. So, if anyone has watched this movie in the theatre, please let me know how graphic it is and whether it would be suitable for her.
