I also think The Quiet Man was one of Wayne's few really well acted films. He fit that part well. He also seemd to have good chemistry with Maureen O'Hara for some reason (he certainly didn't with most of his other female co-stars), and they made a really enjoyable cowboy film with a lot of comedy in it...I think it's called McClintock. And another great John Wayne movie is Red River, where he co-starred with Montgomery Clift. It's almost perfect, aside from the silly ending.
