Redford has aged horribly, why would you hope that?
He's was looking extra crusty in All Is Lost. Good flick if you haven't seen it. He's the only person on screen tho... so it's all Redford, all the time, and not recommended if you're wanting something with some laughs.
Unless you can't stand him, in which case you'll find it hilarious, because he keeps getting the shit belted out of him all the way through.
