To All the 1 star reviews the movie is a Saga, a start to episodes to follow. Yes a lot of story lines and characters but it will unfold in following episodes. Costner is just giving you a chance to see and feel the trials and tribulations that these people will experience. Enjoy the scenery and step back into time and enjoy this movie for what it was suppose to do, set up a saga.
Look at it like the Chosen, except you already know that story I hope so nothing was guess work like this.
