For two peopele who 'supposedly' have a hot/heavy relationship offscreen - their chemistry is non-existent - just like in the 1st installment. Very disappointed. Kristen Stewart continually sounds like she is on the verge of a heart attack with her breathlessness in EVERY seen and looks pained when she kisses Rob Pattinson. His acting is also wooden and filled with too much angst. On the good side, the Volturri were good, added some juiceiness, and the wolves were awesome - in form or 1/2 naked :) They need a new screenwriter and yet another director.
The bottom line here is - if you've read the book, which I have - you will be sadly disappointed. The plot is out of sync from the book, the characters are undeveloped and poignant moments from the book are nonexistent. The acting is so-so. Robert Pattinson is wonderful as Edward, but Kristen Stewart who is perfect for the part in someways - doesn't come across as "in love". And Jacob's scene was so brief it almost wasn't worth it. Save your money for the DVD. Hopefully their will only be a trilogy of movies and the next installment will be better.
