Did anybody else wonder about the ending of My Sister's Keeper the movie? IS ANYONE THIS ANGRY?!?! Spoiler.?

I was pissed. I can't believe they changed the character that died. It ruined the whole movie. The movie was great until the end when she said my sister died that night!!! WHAT THE HELL?!?! I was totally expecting a new scene where they were driving home and got in the crash that caused Anna to die! The maker of this movie can't just change the end like that. It made it way too predictable. In the book I didn't even expect what was coming because it was such a new twist. Instead of the girl with the deadly disease dying she lived because her sister died! I was expecting the conversation between the family about a miracle and wishing your cancer cells away to be some sort of foreshadowing towards Anna's death. If someone who hadn't read the book saw the movie the ending makes it way too predictable. I am so frustrated with the movie. It was doing fantastic until the end when Kate died. The acting was amazing. They may have focused a bit much on Kate and her scrapbook and boyfriend but it was still a great movie that excludes the ending. I'm never going to watch this movie again because I'm so mad about what they did. They ruined the whole message and I wish I had never seen the movie. To sit through all of that depressing stuff and think that Kate was going to live only to have her die?! I only wish the director had stuck to the storyline they can't truly claim that the movie is based on the story because it's not!!!!!

If you have read the book but haven't seen the movie I STRONGLY suggest you do not see the movie. I wish someone told me that before I saw it.
