I saw the uncut version of “Heavens Gate” at an “art theater” a while back. It was not a bad movie. It was just too long. It was about 3-1/2 hours long, with long slow looks at mountains, flowers, long closeups of the stars, etc. The story could have been told in two hours (not cut after the fact) and it would have been a better film.
I saw it when it came out. The waltz scene was particularly mesmerizing it caught the true feeling of the dance. If you’ve ever spent some time in a country and western dance hall you’ll know what I mean.
