It's a very strange, interesting and, at times, genial film. I've seen it in the 125-minutes-long restored version, which seems to be the one circulating nowadays (I don't know who restored it...). It could be viewed as a lenghty and partially boring epic movie, which it is, in a certain sense, but it's redeemed by a couple of very subtle tricks. The opening 45 minutes (about one-third of the film), along with a few final minutes, are set in contemporary times. That is, contemporary a hundred years ago (the film is from 1922). The remaining part is a dream, and dreams within a dream. The oniric atmosphere, which the audience hardly notices - being announced by a very ephemeral titlecard - is broken only at the end. And it's only in the last seconds of the movie that the full meaning of the plot is clarified. If you have a couple of hours left, go for it!
By the by, the film is not "biblical", as I read in some reviews: the history of Lot takes about ¼ of the movie. It can be indicized as a dramatic film, that's all.
