Should I read the books?

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

yes

I would say yes, as I believe u 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 boeken but at least you'll be able to crush the 'If u haven't read the boeken your opinion doesn't matter!' arguement.
Personally, I find the films 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 u watch the last film, as it's my favourite and the best rated of the series.

If u 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 films are better, but its your decision if u want to go for it!
