We saw it this afternoon! Its definitely a slow burn movie but Diane Lane is fantastic and her character and Kevin Costner's character communicate so much depth and emotion with just subtle looks between them. There were some slow portions that I think could have been removed. My biggest gripe is that the antagonists are basically just bad to be bad. There wasn't any depth to them or background as to why they were the way they were so it was a little jarring and not very organic to me. Overall though the scenery is beautiful, it was tense and interesting despite being slow. I'd recommend.

Edited to say that its basically the only "new" movie out right now anyway and we are trying to see whatever is currently showing even if it's not a 10/10 just to help support the local movie theater.
