This is precisely why some fans are annoying. First off, Chris may have a little bit of say in it, but it's ultimately Melissa Rosenberg's script, not Chris Weitz's script. Saying that you now "hate Chris Weitz" is laughable. I swear, when books are adapted into movies, there are the crazy purists, and the more reasonable fans that wait until they see the entire film before passing extreme judgments.
First,saying I hate CW is a bit of dramatic license. I don't hate him. I don't know him. But, I can say that putting a scene from Eclipse in the movie based on NewMoon is just a little ridiculous. Yes, I am a purist, but I do understand that adaptations have to allow for some dramatic license themselves. However, there is a reason why things happened precisely they way they did in both New Moon and Eclipse. I think putting a kiss between Bella and Jacob in New Moon lessens the impact of the first unwanted kiss in Eclipse. Yes, it ramps up the rivalry between Edward and Jacob in New Moon and again for Eclipse. But, New Moon isn't about that rivalry.
And, we know that CW is VERY involved in the scripts he shoots. He saved the Stitches scene when MR left it out, writing it in on his own. I'm sorry but I completely lost faith in Melissa Rosenberg when I found out she left out that scene. My apologies if my opinions annoy you, but that is what these forums are for, to express differing opinions in a respectful way because we are all fans.
