Question to people who have read all 3 books
Contains spoilers
Ok so at the end of the last film/2nd book Bridget and mark darcy are together and in the last book we are given the idea that they got married, had children and a wonderful life together (albeit for a short time). So I'm guessing this film is about her not knowing her the father of her baby is (maybe) or at least she obviously has other love interests. This just doesn't fit with the other books.
Also when I first started reading about the boy I was devastated that Mark Darcy wasn't in it. By the end of the book however I didn't care one bit because it was such a good book/love story. I'm gutted they have chosen to not make that book into a film. I'm guessing it's all because Mark Darcy isn't in it.
