Some people think this movie's too sentimental, and maybe it is. Not for me, though. (See above for the reason I have a soft spot for it.) Besides, it's directed by John Ford, who could do sentimentality in a way that I don't mind. Some people find it hard to believe that three bank robbers would risk everything to save a child. More sentimentality, I suppose, but I can suspend my disbelief easily enough when I want to. I don't mind the religious symbolism, either, even if it does get a little heavy at times.
The scenery's great, as you'd expect, and if you don't need a drink of water by the end of the trek, you're just not human. I don't ever put 3 Godfathers on my list of Top Ten Westerns, but it would have to be close.
