The movie is very long 3 1/2 hours and in reviews I have seen that has been the biggest complaint. I agree it was long and could have been cut shorter but I thought the movie was very good telling the sad story about the Osage tribe. The acting was superior DiNerio played the part of person who hired men commit these killings by paying them and even manipulating them all for wealth that went to him. Even his own nephew was in on it but got in deeper than he thought (won't tell no more but I Loved the movie
