Let me start by saying ITA with dis ms as well regarding the OP.
However, I have a problem with the above. My initial reaction to this was that the OP feels the graphic violence and gore is OK for DD11, but the "dirty" parts weren't. She seemed glad DD11 covered her eyes for those parts. I was glad to read that her DD covered her eyes for most of the movie.
She states that she would be embarassed sitting beside her DD11 during the "dirty" parts but not the gore

I would be for both, and I would have walked - and if I still wanted to see the movie - go at a more appropriate time.
Even if I liked these type of movies, I don't think it is appropriate to bring a underaged child to either violence or other.
I'm not telling the OP how to parent - just hope some of these comments give her another perspective on this situation.
I think kids look up to their parents. If Mom and Dad think graphic violence is OK to watch (and sometimes graphic sex) and parents promote it by taking their very young children to these type of movies, then the kids will on some sort of level think it is OK too. This is where I have the problem.
I would assume that most kids don't enjoy these movies but wear them as some sort of badge of honor that they were able/did see/sneak into at a young age. Alot of posters have said this. "I saw these type of movies and I'm OK for it" Of course. BUT I think as some also posted why do we think it OK to take away the innocence. Let kids be kids. I don't care how mature your child is - they still don't have the capacity at a young age to fully understand. They will get subjected to this stuff soon enough, and at that time hopefully they are informed enough to make those choices themselves.
They have these ratings for a reason. Not just to see how we can disregard them and take our child anyway. I hear so many times, "it was rated R, but we took Junior anyway....." Like that is OK
The OP says she loves "these type" of movies. Great. I don't and I don't watch them. But that is her choice and mine. We are both adults.
"Mother of the Year" - sorry I don't think you'll win this year. But I'd love to hear the comments from your DD to her friends after you took her to this movie........the ones she wouldn't dare say to you.
