I enjoyed the movie. I was reluctant at first, but I enjoyed it at the end. I was afraid the whole "turn live-action peoples into cartoon" wouldn't look good, but it did. It was well played and the scenario was coherent with itself. The theme is good and the action well done (a bit overdone for the final fight scene).
The only dissapointement, but I was excepting it, was the scenario. Putting together half of the Crab with golden pincers (the one in which Tintin meet Haddock, you can notice lots of references to this one with Crabs all around), the whole The Secret of the Unicorn and half the Treasure of Rackam le rouge wasn't a good idea. It get confusing with many things being changed to fit the new scenario. And it's left hanging for a second movie wich would introduce the missing character of the previously named books : the professor.
