Just saw it in 3D. I'm honestly amazed.

The style of action holds true to a cartoon, though the visuals are unbelievably detailed. My dad and I spent the entire film occasionally noticing the tiniest details, like Tintin's freckles, or the wrinkles on the captain's face, or little fragments of dust stirred up and floating around after moving something long undisturbed. Even more broad things, like the general framing, were great. Action scenes feel intense, but not through obnoxious shot changes or anything like that. They're just genuinely great, exciting, and immersive, especially a chase scene that really makes you feel like you're riding along with the characters.

My only real complaint with it is, on occasion, the sound. Specifically, Snowy the dog makes some kind of noise every second he's on screen, which can get kind of tiring. Tintin has a habit of thinking aloud too, which I suppose is fairly true to a nostalgic style of adventure based on a comic, but it feels somewhat misplaced among the stunning, modern visuals.

All-in-all, though, the film is just immensely fun from start to finish, and I'd highly recommend it.

Oh, also, happy Christmas to the lot of ya.
