I enjoyed this so very much.Now, I'll say that (to use fanfic terms) there was a bit of hand-waving. And the plot is not for the faint of heart (he BROKE the timeline! the Avengers must fix it!). I laughed like a mad woman and squealed with a twihard at the Breaking Dawn premiere. Not that it didn't have serious moments as well (Tony has an almost heartbreaking moment which was amazing).
