Eclipse was my favorite book in the series, and accordingly this movie was my favorite so far! The acting has much improved, and everyone's attitudes are much less angsty and emo than they were in New Moon. The movie was incredible overall, but I felt like the scenes were very rushed and had I not read the book I would have been confused as to what was going on and you miss many of the nuances that were more thoroughly explained by Stephanie Meyer. I'm still going again... probably more than once! :)
Many people are complaining about the lack of action and suspense in this film, however if you've read the book you realize that this story is more about character development and maturation than plot. This series of events (as it was in the book) is mostly a set-up for the last two movies that will come from the seventh book, but that is made up for by the increase in comedy and entertainment. I would definitely recommend my friends to go see it.
