Eclipse was by far my favorite book in the saga. The movie did try to stay true to the book as much as possible but I feel it still lacked what made the book great.
The things I feel is missing from the movie is suspense and chemistry. The love triangle is back and was a bit more entertaining now that all three of them are interacting more. But I still find the lack of chemistry between the characters glaringly obvious. I often had to think about my feelings back when I was reading the book to fortify what I saw on screen. In my opinion, they used too many words (and dialogue from the book) to describe what’s going on instead of SHOWING (acting) us what’s going on.
The climax in the book was what made Eclipse my favorite of the saga, however, I can’t say the same for the movie. The climax was disappointing and anti-climatic. Such dramatics for a walk in the park.
