“Strayed” isn’t really Cheryl Strayed’s last name. The author and subject of “Wild” was originally born Cheryl Nyland, and eventually decided to change her surname after years of pain and a particularly wrenching divorce – and, if the movie adaptation of her novel is to believed, it was literally plucked out of the dictionary after careful consideration – into something that echoed, well, how she had strayed from her path, and possibly her wish to get back on track. When we first meet Cheryl (Reese Witherspoon) in Jean-Marc Vallee’s lovingly crafted Wild, she’s bloody and bruised and gasping, perched high atop a mountain, desperately pulling off her too-tight hiking boots to reveal a blood-soaked sock and a big toe that’s in bad shape. Terrified and alone, Cheryl yanks loose a cracked toenail, practically spits in pain and jostles loose a single boot, which tumbles down the rocky incline, never to be seen again. Cheryl’s next move is perhaps a bad one: she stands, screams and chucks her other boot after it. How do you get back on track after that? You stand and you yell and you chuck your other boot. And then you keep walking.
