I found the following quote when I looked up the "R" rating, "As reported on Box Office Mojo, "Deadpool" has been rated R for ?strong violence and language throughout, sexual content and graphic nudity.?
I have been a Christian for 44 years and 30 years ago I probably could /would have watched it then, but today it would sicken me. I don't see how someone that is indwelt with the Holy Spirit could sit and watch something like this. Piper is correct in my opinion. I regret some things I watched but you can't go back and undo what has already been done. I would say err on the side of caution.
