I have difficulty watching "The Prince of Tides" although I thought it was a good movie and there is a scene in the movie "The Crow" that I could have done without seeing as well. The movie "The Cell" also bothered me. Any violent movie or television show which depicts or alludes to child abuse, rape, gang-rape, physical violence etc. are off limits for me.
I was once at the cinema watching the previews before the main feature, when I lost a period of time and sort of 'blacked out' for a few minutes. As it turns out, there was a violent rape scene that I totally missed as my brain fought to block it out. It was like I went temporarily blind or something as I "checked out". So when a movie is rated "R" or a show recommends viewer discretion, I take it seriously and try to screen out offending material (usually opting to forgo the movie/show completely).
I do like a good ghost story, but I have a dislike for the horror movies that I used to love so much. They give me *intrusive thoughts; I see brief glimpses of horrible things in my minds eye (unwanted visuals), I get paranoid, end up locking all the doors and windows then, I can't sleep or have nightmares. Think I will stick with Disney movies and romantic comedies.
