There's a lot going on which can make it a little hard to follow. The majority of costumes/ hair styles of the main characters are not accurate to the 1850s/1860s. In many cases it's just 1 or 3 things that are just off. Garment being worn incorrectly, loose hair, wrong parasol for the period, style of dress off by 20 years, etc. However most people aren't seeing this movie for the fashion or accuracy to life at that time...
So, as far as the storyline it seems a little predictable but only time will tell. I like how the Apache aren't being portrayed as the stereotypical bad guys and the story tries to show both sides of a complicated situation.
Would I see it in thearters agian?
Probably but more so I can get a better handle of the storyline/characters because I feel like I missed something. Overall not a bad movie and I enjoyed it for what it is and hope it gets better from here. I'd really like to see more films in this genre
