I could go into great detail to explain why I love this movie and why it continues to make me think, but instead I'll just pass and say it was pretty sweet. The ending was a little disappointing for me, but the overall morbid/depressingness of the movie (and the action scenes) made it worth seeing.
I was a Twilight fan until all the raging fangirls murdered it for me... but that's about it. :B I didn't go through every little detail of the book, or series. (Though the ending disappointed me greatly) I just went through it without a care back when it wasn't popular and enjoyed it, simply, for what it was. Just a nice fantasy romance. Nothing more, nothing less.
All this Twilight bashing makes me sad. There's just gonna be another huge fad similar in a few years or so, and the whole cycle will start over again.
