The franchise is over. I can go in to great detail reviewing this or I could just save my time. If you love the franchise, you have seen it or will. If you don't - you won't. I read the books and saw the movies. This one was much more tolerable that Part 1 of Breaking Dawn and I was glad that they did a twist at the end that gives much more satisfaction (and a pretty big laugh after realizing it) then the last book did.
Like I said - if you are going to go - you will. If you are not - you won't. No reason for me to recommend whether or not you should.
