Hey, I saw it, it wasn't so bad after all :-)
They shuffled some scenes from various albums (to introduce more characters in less time), but the story remains consistent.
The graphic style is a good compromise between the canon style and photorealistic CGI.
They turned Sakharine into a villain, but eh, could be worse.
Also the plot twists written from scratch (I won't spoil here) aren't too goofy nor cheesy.
I'm a Tintin fan, and I must say I was expecting the worst coming from Hollywood (see how they burnt the Smurfs license to the ground). But Spielberg and the crew did a good job here. You could even say he finally found here the space to do what he wanted to do in Indy 4 and shouldn't have (epic-yet-funny chases, anti-hero climaxes, etc.)
