can somebody explain to me what they mean about Breaking Dwan being R rated অথবা RG-13 rated.

If আপনি read the movie, I think আপনি can understand why.
*Spoiler* (If আপনি haven't read the book don't read this) :
It's because of Edward and Bella's honeymoon and their first time really together :) :) ♥
And because of the Bella's violent birth scene of Renesmee..
*End of spoiler*
So I trully hope that it wouldn't become an adult movie because that's my পছন্দ book from the series and I'm 14 years old, although till the movie I will be 15 years old - And I want to see it BADLY ! ! ! :) :)

It's because of the adult nature of some of the scenes in Breaking Dawn; such as *spoilers follow*

the honeymoon scene; the birth of Bella and Edwards daughter; and the প্রণয় scenes following Bella's transformation.

*spoilers end*

As I am 20 years old I hope that it will be rated that way; so that not only can they put the all the content from the বই in the movie without worrying about it not being PG-13 enough; but also so I can enjoy going to see the movie without having tons of Young teenage girls screaming at every moment. I went to see Eclipse and I could Barely hear the movie over all the teenage girls screaming. No Offense; it just wasn't enjoyable to watch with all of that and it shouldn't have to be that way. If they would Not scream; then I wouldn't care who goes to see it.

It is because of the honeymoon. K-Stew was caught wearing a bright fluorescentgreen bikini with the straps tied up and it actully stuck to her so in the movie it will appear that she is topless.
