Fans of the later Tintin books will find this one tough going. Visually the character is drawn unevenly (sometimes scrawny, sometimes a burly fighter). His "adventure" is a series loosely connected vignettes of anti-Communist propaganda rather than a story per se. This book does introduce many of Tintin's standard escapes and disguises used in the later books but is otherwise only of historical interest.
