Twilight Series ...

I know this came up several months ago but what are ya'll's opinions ("ya'll" is a word, let's get that out of the way) on the 'Twilight' series, by Stephanie Meyer?  I read the first book yesterday (yes, in 4 hours) and I'm not sure I want to commit to this series.  It was good, and obviously a pretty easy read, but seriously, do I want to get emotionally involved here or not?  I can't seem to make up my mind if I want to make the emotional investment.  Or will there be and emotional investment?  Anyway, I know you gals won't steer me wrong.
