Most of these reviews seem to be a year old. My wife and I re-watched the movie this past week and ... ah ... the ending has been changed. A LOT! Evidently just recently.
The thing that struck us the most is how little we remembered of the first time we saw it. I had a continuous feeling thru the film of "I don't remember this." That tells me the film was not memorable. I blame using super-fast imagery instead of storytelling.
The good news is, now you get to watch it again and it will feel like a whole new film, even though only the ending has actually changed.
