The tumult of love in Terence Davies' 'The Deep Blue Sea' is given extra propulsion by a masterful Rachel Weisz."The Deep Blue Sea" shows us where love has gone, reveals the dark and despairing places where ardor has shipwrecked and run aground. Exceptionally well-made and completely fearless in its depiction of the widest range of romantic emotions, this is a film as fiercely committed to passion as its heroine, and that's saying a lot.
