For Michael Farr, Tintin and Alph-Art provided "an almost perfect ending to more than fifty years of defying danger, threats to his life and a succession of villains". He believed that it was "full of a vigour and enthusiasm disappointingly absent from the two previous adventures", and that as a result "it promised to be Hergé's most accomplished Tintin story for twenty years". Jean-Marc Lofficier and Randy Lofficier stated that had the story been completed, it "may have turned out to be a smaller-scale, unpretentious yet far more exciting and true-to-life adventure" than various recent volumes. Hergé biographer Benoît Peeters felt that "despite its limitations, and perhaps on account of them, this unfinished story fits perfectly alongside the other 23 Tintin adventures. Full of promise, it ends the series admirably by leaving the last word to every reader's imagination". Philippe Goddin opined that Tintin and Alph-Art'''s opening "promised much, coming like new breath".
