I always try to keep an open mind when going to a movie adapted from a book. I have even read this series (several times over). I enjoyed this movie and will purchase the DVD when it comes out.
However, I must say that some of the dialogue is cheesy, some special effects hokey, but the sudden irrational love that starts between Bella and Edward is shown. Definitely something portrayed in a book easier because it was a little sudden in the movie. The acting was OK. Rob Pattinson tried too hard to be all angsty and torn, Kristen Stewart was a twitchy teen, but everyone else was totally endearing.
This is worth the 2 hours and 5-10 dollars to see it. Be a part of the phenomenon!
