Tintin au pays de l'or noir
Harry Thompson described "Land of Black Gold" as a "patchwork effort", believing that the final result owed little to the "story's original satirical thrust". He praised Khemed as Hergé's "most successful imaginary country", something that he attributed to its "geographic accuracy" and to the "realistic parody" of Arabic names. However, he criticised the way in which Haddock had been integrated into the story, deeming this to be "the least satisfying aspect" of it. Believing that it offered a "fine swansong" for the decline of the Thom(p)sons as central characters in the series, ultimately Thompson felt that "Land of Black Gold" retained a "somewhat fragmentary air". Differing from Thompson's assessment, Hergé biographer Pierre Assouline felt that the inclusion of Haddock into the story was successful, "precisely because [it] defied all logic".
