will bd be a good movie

me and my friend were talking and she says she cant wait for breaking dawn the movie but im not so sure do u think bd will make a good movie or will they have to add stuff to make it good

i really don't know because it all comes down to the director really.
also what age group they are aiming for because as we all know the book contains scenes that aren't at all apropriate for the seven year old fanbase that exists. its ok for them to read it and a have their own idea of whats going on but actually seeing it might be traumatising(ruh-nay-nays birth) or too mature (the making of ruh-nay-nay). i have a feeling they will make it a PG or a 12 (Uk certificates basically ok for kids to see) so they make more money but really i want a gore-fest nessie birth lol.
