I can't view this as anything but a disappointment. It was a reasonably entertaining movie, with some great moments but as someone who knows the Tintin books inside out, it was a rather jarring experience. The movie started off as a modified version of 'Secret of the Unicorn', then jumped into the story for 'Crab with the Golden Claws', then back and forth for the rest of the movie.
We got all the familiar Tintin motifs and characters (except for Professor Calculus) but the result is less than the sum of it's parts. It was as if it was song made by mixing a Led Zeppelin song, a Pink Floyd Song and a song by Sarah McLachlan... despite all the beauty of the individual songs, the result will be something ugly.
