 Architectural critic Witold Rybczynski wrote in 2006 that the monument is "poorly done", likening its precast concrete slab walls to "mammoth Lego blocks", and commented that Kennedy "deserved better than this".On the 50th anniversary of Kennedy's assassination, "Dallas Morning News" architecture critic Mark Lamster called the monument "a disappointing product of the city's ambivalent response to the events of November 1963" and said that Johnson lacked "an animating vision that might have produced an inspiring design.This, in turn, was compounded by a lack of experience".
