what is critics on english literature

Are you referring to T.S. Elliot? Eliot is one of the greatest literary critics of England from the point of view of the bulk and quality of his critical writings. His five hundred and odd essays occasionally published as reviews and articles had a far-reaching influence on literary criticism in the country. His criticism was revolutionary which inverted the critical tradition of the whole English speaking work. John Hayward says:

"I cannot think of a critic who has been more widely read and discussed in his own life-time; and not only in English, but in almost every language, except Russian."

If this is just a general question, English Lit. Criticism is simply the evaluation and interpretation of specific works within English lit.
