There's a saying for what happened in the movie, cuae they actually did the parts justice IMHO. You can't make a purse out of a sow's ear.

Basically, if the characters are badly written, and so is the plot, then you CAN'T actually make a good movie out of it. That, and they tried to make the series an action series when the focus was always more on the romance. Insteed of TRYING to make it romantic, they actually successfully made Edward an alien freak, and Bella a zombie, makign all the secondary characters INFINITLY more interesting than them, which is wrong. In the book, the secondaries get meantioned inbetween paragraphs of how beautifull Edward is. Dare I say it- the movie would ACTUALLY been beter if it were more like that, then the main characters wouldn't be so dull.
