It nicked the fat (Spoilers)
Now I've never been a fan of John Wayne, mostly because he rarely acted beyond being the "John Wayne character", the "right-wing, manly-man" character. He stuck to that character quite rigidly and so could not develop into the specific character for each role. That being said, I still decided to check out "Red River" (hey, it's got Montgomery Cliff!) and I got to say John Wayne actually impressed me. The dark brooding atmosphere, the homo erotic gun banter, the talented cast, and the fact that John Wayne was for the most part playing against type. Even John Ford was surprised by John Wayne in this film. I become engrossed in this dark tale of determination/obsession. Then Joanne Dru comes along and annoys the living hell out of me. I can hear the studio heads going "We need a love interest for Montgomery Cliff, one that's not John Ireland, so shove one on screen." The notion that Monty (or anyone else) could stand her let alone fall in love with her in course of eight hours nearly wrecks the whole tone of impending tragic doom.
Then the final showdown comes, the culmination of the stubborn quest for revenge and pride is at last and unavoidably at hand. The three best shots in the West (Montgomery Cliff, John Wayne, and John Ireland) square off. John Wayne approaches Montgomery Cliff with murder in he's eye and John Ireland leaps into action, shooting John Wayne who fires back. Both men are hit and felled, John Wayne staggered up and goes on towards Montgomery Cliff and then... and then...
They made up! What?! They admit they love each other and to top it all off John Wayne says that the gunshot wound he received from sharpshooter John Ireland isn't fatal, it isn't even bad at all, "It just nicked the fat". No! You just got shot! You just spent the entire movie in an unyielding quest for murder! And now you're all one big happy family with a new daughter-in-law, and minus John Ireland who is never seen or mentioned again and presumingly is dead. No! I literally got out of my seat the shouted at the TV "No! You gotta to be *beep* kidding me!" The film cops out on the sad ending it deserves and needs choosing instead to pull a complete and fraudulent 180 from dark and epic to 'ah shucks wasn't that an adventure.'
