Sci-Fi del Grande Gatto: Twilight: Breaking Dawn Part Two

Spoiler warning: The review does contain a spoiler for the movie's big "plot twist." It's included because it's so infuriatingly stupid I couldn't not mention it.

The final Twilight movie sucks. Shocking, I know. If you end up seeing this movie, why? Whatever the reason, tell us what you think of it. Seriously though, why?
