Best Westerns

What are the greatest Westerns ever?

Here's my list:

Rio Bravo (Criminally underrated. Howard Hawkes answer to High Noon. Kozy)
Jeremiah Johnson (Utterly unique. Every man's aspiration. I was watching this last night and thinking, cabin in the woods, hmmm...)
Tombstone (Geat cast. Two words Val freakin' Kilmer)
Silverado (Great fun)
The Searchers (Greatest Western ever. Wonderful to look at. John Wayne should have won an Oscar)
Dances with Wolves (One man's spiritual journey)
Geronimo (More or less historically accurate. Jason Patrick is great)
Unforgiven (Clint Eastwood's greatest. Two ours of tension build up, two minutes of pyrotechnics)
*We are curious for European opinions on this.
