Haven't seen the film yet, but planning to go this week. Seems like Tintin has been collecting mostly praise in Europe, and some friends of mine have said good things about it. The tempo seems to be very fast, and some negative reviews have claimed that "this is not the Tintin we loved", but hyperactive rollercoaster that loses the charm of the original. Well... I'll tell later what I think, being a fan of the comic-strip from the late 70's.
I thinks it's pretty clear that if any newcomer picks a Tintin comic-album after seeing the film, they will think the comic-version of the film is pretty lame and slow... For me, the photorealistic Tintin looks a bit strange. The style of the comic is a combination of cartoony and realistic, with flat colours. I originally kind of hoped that they would have invented some similar effect to the film, but of course they went to more realistic direction.
Making a film about Tintin is... almost like somebody trying to make a film about H2G2.
i was wary of these points of criticism, too. but i have to say, the animation looks just beautiful, and while at first the 3d-rendering of our beloved 2d-characters seems a bit strange, i warmed to it very quickly. as to the action, actually i didn´t feel overwhelmed by it at all. there is one chase in the middle of the movie (where it departs the most from the known storyline, which isn´t a problem imho) which is pretty impressive, but also very apt, considering that we are no longer on paper. i feel that bringing tintin to the big screen needed a bold vision, and this movie has brought us this, while still retaining the charm and heart and humour of the original comic book adventures. the characters work and have a "chemistry", especially the trio tintin-snowy-haddock just clicks.
one thing i know: you´ll love the intro, which is like a tintin mini-adventure very much in the style of the comic books.
