Blazing Saddles could easily be included.

If you're going to include comedies, how can you leave out Blazing Saddles?
I intend to live forever.
So far, so good.

1: Tombstone
2: The Shakiest Gun in the West (Give comedies their Due)
3: Silverado
4: The Good the Bad and the Ugly
5: How the West was Won
The Revenant was a HORRIBLE movie. Watching Leo crawl and grunt for 2 hours is not my idea of entertainment. For those who like crawling and grunting I'm sure he did a fine job of it.

And in no particular order:
Tombstone
Magnifcent 7, The (1960) (quotable as Casablanca, or Hamlet even)
Open range
TGTBTU (obviously)
Rio bravo (obviously)
Dances with Wolves
El dorado
Silverado
Shane
The big country
Maybe unforgiven too.
"If at first you don't succeed, then maybe sky diving isn't for you"

Tombstone

5. Tombstone

1. Hondo
2. Unforgiven
3. Death rides a horse

In no particular order:
True Grit (2010)
Open Range
The Assassination of Jesse James by the Coward Robert Ford
Outlaw Josie Wales
No Country For Old Men (a modern western)
Unforgiven
Lonesome Dove
Tombstone has some ok scenes and dialogue, and some cringingly bad ones, IMO. It's a little too cartoony to make my list of favorites.

1. The Good, The Bad, and The Ugly
   2.Tombstone
2. Rio Bravo
3. The Outlaw Josey Wales
4. Blazing Saddles (Sorry, I love that movie)
   You can also add: The Revenant, The Hateful Eight, and Django Unchained. (I am a Tarantino fan.)

   If wanting illegals deported makes me a bigot - then wanting a rapist jailed makes you a sexist!

Is that not why you are here? ; )
