It almost feels like someone adapted Shakespeare to a movie set in the near future where the economy had gone to hell and the US is almost without water. The film is slow, really slow, so that in two hours you don't see much. Paradoxically, some of the important scenes are rushed through, while others, related to character emotions are prolonged.
To me it felt both as a well done movie and a boring one. The practical effects, the acting, the shots, they were all excellent. The pacing and the story, on the other hand, a bit disappointing. I guess you have to be in the mood and you have to like the technique of film rather than just look for a story to entertain you.
Bottom line: Hard to call it a bad movie in any context, but only part of the viewers will be glad to have seen it. Let it go at its own pace, watch it from start to end, try to grasp the vision of the writer/director. Hope it works for you.
