The new "King Kong" I think rewatches VERY well. I liked the original well enough, but the new one has really stuck with me and I often have the urge to see it again. It gets better every time -- I've probably seen it four or five times over the years. I highly recommend it. I bawled, of course, but I'm a female. I'll cry at nearly anything. I wept in "Galaxy Quest" when Alan Rickman made the deathbed promise to Quiddick (I think that was his name) -- "By Grabthar's hammer ... I will avenge thee!" *sniff*
But the new King Kong was very well done and I think deserves a place as great movie -- I think it will wear very well and get better with time.
