Awfully bothersome BY CELIA McGEE
A year or so ago, the Manhattan Theatre Club imported the English play "House and Garden," by the delightful Alan Ayckbourn.<br /> "The Good Wife Strikes Back," by the best-selling and, well, very English author Elizabeth Buchan, has many of the same details of Ayckbourn's civilly dark play. Did Buchan see it? If she did, she took away only its most shopworn aspects.
