A.O. Scott: “For those of us who believe that any movie worth seeing is worth arguing about – and vice versa – summer can be a season of malaise. … So it is cause for rejoicing when something” – i.e., The Help, The Future, and The Tree of Life – “comes along that raises hackles and polarizes opinions, stirring up passionate quarrels, both private and public, in which more seems to be at stake than who liked what.”
