Should I read the books?

Well if te liked the movies,then I say yes te should read the books.For the most part the Film follow the books.The people making the Twilight Film knew it was important to the Twilight fanbase be true to the books.

yes

I would say yes, as I believe te should never turn down the chance to read, whatever type of book it may be. I don't know if you'll necessarily like the libri but at least you'll be able to crush the 'If te haven't read the libri your opinion doesn't matter!' arguement.
Personally, I find the Film to be better than the books, because there is much less insight into Bella's thoughts (obviously, as it's a movie) which I find to be annoying at the best of times and downright bitchy at the worst of times.
I'd also recommend te watch the last film, as it's my favourite and the best rated of the series.

If te get sick easily I wouldn't. I have a pretty strong stomach, but when I read Renesmees birth I almost threw up. I'm pretty sure the Film are better, but its your decision if te want to go for it!
