Two poems I read yesterday were dissatisfying for opposite yet complementary reasons: one was all language, not anchored to anything real; lovely language but not about anything; no subtext. The other poem described a real event but there was no language, also no subtext. Neither was larger than its limited self. Both of the poets have said at various times that they don't like to get specific; they don't want to name the thing or the time.
Update: I just found the perfect quote for my response, from James Parker in The Atlantic: A random-feeling extrusion of lyrical matter, like something that might come out of the tube when you pull the lever marked POETRY.
P.s.: He was talking about the very young Robert Frost.
