I have never watched the TV series, and so this film was really new to me, and I loved it! I don't think you really need to watch the TV show because they really give you all the characters in the first 5 minutes and they each leave a lasting impression. Sarah Jessica Parker's character is about to get married, but he doesn't show up at the alter! She then has her entire honeymoon that she doesn't want to go to waste and so instead her girlfriends go along to try and cheer her up. It's such a fun film that you can rewatch so many times.
