Three Godfathers is supposed to be one of Ford's ' lesser' westerns but I don't agree.
The desert cinematography is really beautiful, even by Ford's always impeccable standards.
The story is sentimental for sure but works for me . More important it's one of those films that sticks in your head and rewards multiple viewing.
I've got so many favourite westerns that I'll not attempt a list. Ford is my favourite and I've watched his westerns many, many times.
I'll put in a word for the undermentioned Sergeant Rutledge. This one also uses a flashback structure like Liberty Valance, has a court case and, naturally, amazing photography and lighting.
These are good ,
