Underrated masterpiece

Do only i think that this movie should be rated much higher? I know that 8,0 is not that bad, but not enough for great movie like this. I mean, almost everything is brillant or great here, from message about solidarity and friendship (even among the ultimate scoundrels like film's protagonists) through brillantly shot scenes of train robbery and at the end one the greatest shootout's in history of cinema. The film was at the time revolutionary in terms of montage and screen violence. And of course it changed cinematography forever (After this films it was impossible to shot naive classicals with John Wayne like Rio Bravo again) So therefore i think it's seriously underrated movie that should be next to Unforgiven, For a Few Dollars More and Treasure of Sierra Madre in top 250 ranking
