I'll start by confessing to knowing next to nothing about the original Tintin comics. I have seen the character before, but never read a single story. But this was an engaging caper with good guys, bad guys, humor, and adventure.
Tintin (Jamie Bell) is a journalist, and judging by the clippings on his wall, he's had quite a few adventures. He buys a model boat at a flea market, and that immediately enters into an adventure surrounding a hidden message and sunken treasure. Along the way he meets Captain Haddock (Andy Serkis), who is drunk enough to power an airplane engine with his breath (BTW, I have to give kudos to an ostensible kids movie that isn't afraid to show drinking or have the young hero use a gun). The action rarely lets up and the caper is smart as well as fun (a "sword fight" with giant cranes is particularly amusing). Beyond that, I can't really comment further. As I said at the start, I'm not a Tintin expert.
Oh, and as one final point, the 3-D was very well done, but not really necessary. If you're a fan of 3-D, it's worth it. If not, you lose nothing by seeing it in 2-D.
