Exhibitor Relations Co. first listed the news about the rating on social, and it’s not exact a shock the movie was given an "R" by the MPAA. In fact, the latest movie will feature the Adult Loser Club and not just the kids, so I would expect things to get more horrifying. It’s also based on the second half of Stephen King’s famously violent and distorted IT. It certainly isn't the most graphic or disturbing reason for an R-rating we've seen this year, however.
