Whayya think? How'd I do? 
1. The Calculus Affair (18) – all the series’ best elements, and none of its weaker ones
2. The Castafiore Emerald (21) – a masterful smaller-scale piece that’s as exciting as any
3. Land of Black Gold (15) – lots of fun, diverse settings and a still-scary political yarn
4. Tintin in Tibet (20) – a wonderful, touching tale, the only one with no villain!
5. King Ottokar's Sceptre (8) – the last pre-Haddock adventure is also the best
6. Tie: Destination Moon (16) – an excellent set-up to the next; Explorers on the Moon (17) – follow-up is just as strong
8. The Red Sea Sharks (19) – perhaps the least original later adventure still thrills
9. Tintin and the Picaros (23) – what it lacks in exuberance it makes up in maturity
10. Red Rackham's Treasure (12) – a splendid payoff to its ground-laying predecessor
11. Prisoners of the Sun (14) – underwhelming payoff, but otherwise terrific adventure
12. The Seven Crystal Balls (13) – genuinely suspenseful horror is ultimately a bit silly
13. The Blue Lotus (5) – a humane, informed and exciting tale, but, alas, unrefined artwork
14. Cigars of the Pharaoh (4) – not as insightful or researched as later capers, but just as fun
15. The Black Island (7) – lively and charming, if somewhat thin
16. The Crab with the Golden Claws (9) – Haddock’s introduction is great, the rest okay
17. The Secret of the Unicorn (11) – engaging story, but not much local color
18. The Broken Ear (6) – back to pre-Lotus slapstick plots, weaker artwork, but strong satire
19. The Shooting Star (10) – a fun caper, though ultimately a bit of a shaggy-dog one
20. Tintin in America (3) – visually inventive and amusing, but overly cartoonish
21. Flight 714 (22) – aliens? Forced amnesia? A wussified Rastapopulous? Lame.
22. Tintin in the Congo (2) – a youthful error in racism, though visually dynamic
Not ranked:
Tintin in the Land of the Soviets (1) (no color edition, haven’t read it)
Tintin and Alph-Art (incomplete, haven’t read it))
