Everyone is saying it's bad because of how disappointed they were of how Stephenie Meyer ended the series. I am a huge fan of the series, and the first 3 blew me away! I have read Breaking Dawn, but I WILL NOT GIVE ANY SPOILERS, if you're wondering ;]
Anyways, it's people's opinions, and some have said that it was awesome. However, I think that it was rushed, and the plot was random, sort of. Although I wanted some of the things to happen, it seemed so... "out of control" as in there were a lot of sexually implied scenes. I thought everything and everyone was out of character.
The reviews on Amazon were around a 2 and a half star rating. I felt disappointed that a series as fantastic as this ended how she wrote it. Some of the characters didn't seem like themselves, like their personalities had been changed completely. But, it is her book, and I respect her for choosing whatever plot line Stephenie Meyer wants.
But if you want the book, please buy it if you're prepared for a couple of shockers, my rating would be around a 2 and a half as well but some liked it, and you may too. So give it a shot =]
**Note: I totally agree with Sinead! I have too read some fanfictions and it does seem better. And the part where Edward and Bella have a child, even though she says that they could not... that was out of place. If she wanted that to happen at least research some facts up like a "dhampir", which is born from a human mother and a vampire father. Or something to make it all fit in!
