Twilight; movie vs book?

I have never in all my life in reading book and watching the movie( not even in Harry Potter) been so disappointed in the Twilight "movie" It was the cheapest and undeveloped movie I have ever had the displeasure of watching. The director should be fired and the Guy the played Edward should be replaced. Bad acting. The love between Edward and Bella did not even come close to how it was portrayed in the book. What a waste of film. I want my money and time back! Some crucial and critical parts in the book is missing from the movie. I was so angry!! People who didn't read the book before watching the money can't sympathize with me. Who else thought the movie was a disaster?
