Even before the first episode was broadcast, Brian Lowry in
Variety attacked the show, saying that the guest comedians were "second-tier" and that the set "resembles a cut-rate version of
The Weakest Link set" and that "Comedy Central's programming usually falls squarely into the sublime or the ridiculous, so consider
Root of All Evil a rare tweener in terms of quality—one that proves a whole lot of Black is preferable, albeit marginally, to a
black hole." Attracting about 2.3 million viewers, the debut episode was the most-watched premiere episode of a
Comedy Central series since the premiere of ''
Chappelle's Show'' in 2003 and topped the demographics for male audiences ages 18 to 34. Mark Dawidziak of
The Plain Dealer wrote in his review, "I'm a sucker for a good Lewis rant, and sometimes
Root of All Evil would benefit from more Lewis fomenting and less formula. For as long as it's around, though, it does make a good fit with a Comedy Central lineup that includes
Jon Stewart,
Stephen Colbert,
Sarah Silverman and, of course,
South Park." The 3rd Annual Independent Investigative Group
IIG Awards presented an award to
Root of All Evil recognizing the promotion of science and critical thinking in popular media on May 18, 2009. ==Cancellation==
