Wayne played the same character he’s been playing for 40 years. And I thought Campbell was awful…like Sofia Coppola in Godfather III awful. Some of Wayne’s better performances that may have actually deserved an Oscar:
The Searchers (by far his best, IMO)
The Quiet Man
Rio Bravo (with an extra star for having a smoking hot Angie Dickinson)
Sands of Iwo Jima
The High and the Mighty
Frankly, True Grit was about Wayne’s 20th best performance.
True Grit wasn’t even one of his best westerns. Searchers, Rio Bravo, Sons of Katy Elder, The Man Who Shot Liberty Valence, McClintock!, War Wagon and others that don’t come to mind were all better.
Worth reading? Maybe. I guess it depends on how dedicated to the universe you are. It’s not great but there’s some interesting developments and it ends on a cliffhanger.
