I think I can understand
snowy_1001's opinion. Generally, this thing also happens to novel fans (like Harry Potter fans). Just remember each time when the movie was premiered, another thing you might heard besides the movie's review is the fans' complaint on how inaccurate the movie compared to the film. No matter how hard the movie maker team tried, a movie adaptation compared to its source (be it a novel, comic, true story etc.) will never be accurate. So, just accept the flaw anyway (or if you are afraid to disappoint yourself then don't watch the movie at all ;D).
A side note anyway, we are not only the one who 'quarreled' about this Tintin movie, even the most prominent Tintinologist, such as Michael Farr and Nicholas Lezard have different view on this movie. Lezard, as a purist, thought that this movie was somewhat a nuisance, yet Farr, on the other hand, thought that this movie was indeed excellent. This proves that we are not the only one experiencing this differences, even the top Tintinologist also experiencing this. And this also proves the points
laloga and
Ginger_Tuft has mentioned.
Anyway, if you curious about what the expert Tintinologist said, you can read about them

Moderator reply: Yes, linking to a news website like this is fine, so thanks for sharing that. (Btw, I've fixed your weblink which wasn't quite working before, and I've turned the rather lengthy web-address into a URL link on the word "here" - something you'll find you can do with that right-most button on the tool bar just above the message box.)
Also, there's this
forum thread specifically on the Tintin movie's press reviews, which may interest you.
