he's up against a National Monument in the form of John Wayne, who is so singular and iconic a presence that there's just no way he can top Wayne's performance, or make Rooster as memorable by going in another direction. Plus Wayne, in playing Rooster, was playfully subverting an image he'd inhabited for decades and brought a huge amount of subtext to the role simply by being who he was. That's not there with Bridges simply because he's never been THE western hero that Wayne was.
