Yeah well it helps if ur a girl lol.
The film is pretty good but they left out tons of scenes (obviously due to time limits and such) which are included in the book.
The books are... well yeah... absolutely amazing. I think for the girls it is the "
OMG OME (Oh my Edward lol)" factor and the love bit, but I also think that the plot to quite a few of the books is really cool... especially Eclipse is almost like a romantic detective novel lol.
So if ur a guy I can understand y ur confused lol. If ur a girl then u seriously need to read the books to understand lol.
I'm not saying that guys shouldn't read them (I have many guyfriends (not gay ones) who like them as well) but they tend to find them a little soppy and a lot of eye-ball rolling goes on

I agree with you though, the film wasn't that brilliant in my opinion (and no I did not go in there thinking "this is never going to be as good as the books", I actually really wanted to like it but they mushed too many scenes around.
Hope that long essay on Twilight helped lol.. feel free to leave me a comment
