I wouldn't have agreed 11 years ago...but yeah after sitting through it again tonight it shot up my list of all time Westerns...I can't agree about it being a top 10 of all genres though.
I still say Open Range is at worst my co-favorite..I love that movie, I watch it at least once a year...such beautiful beautiful beautiful cinematography and a great timeless story and characters..Duvall and Costner kill it.
My co top three...in very slight order..
Tombstone
Once Upon a Time in the West
Open Range
