How do you know when the filmmaker has done their job? When you know how the movie turns out, but you’re still worrying about the protagonist and hoping they succeed. “Wild” (2014) is one of those movies. Reese Witherspoon is a young lady with a lot of baggage who is searching to find herself. So she and her humongous backpack set off on a 2,600-mile hike. The symbolism is heavy-handed, but the movie is not. Wisps of her dark past mingle with the outdoor beauty so as to not repulse you by the former or bore you by the latter.
