I think "Return of the King" is my favorite because all the plots, subplots, and loose ends finally make sense in the sweeping, epic conclusion. I cry through half of it, which usually helps me rate a movie higher. :-) Though I do have to say that the multiple "endings" do get a little tedious . . . I would have been okay with the coronation scene being the end. Nevertheless, each character's mettle gets tested in ROTK, and their successes are truly inspiring.
