Equus (1977)

Risible Freudian absurdity which just happens to contain one of Richard Burton's most delicious howling performances and Jenny Agutter's least inhibited, and is therefore of some interest to connoisseurs of either; verging on irresistible to connoisseurs of both.
As drama it's uphill all the way and hard to warm to even as claptrap, since it makes the fatal error of depicting the central act of horse-blinding realistically and explicitly. In the original stage play it was done 'symbolically' - ie: with cavorting mimes done up like horses. That was stupid; this is just horrible.
