The script shows a tremendous love for the world of Tintin, and brings a lot of humor to the table. The script had a first draft by a pre-Doctor Who showrunning Steven Moffat, and was finished by Edgar Wright and Joe Cornish. The screenwriting credits alone were enough to convince my wife to watch it.
The characters are interesting and complex, with deep reserves of funny. The most obvious example is Andy Serkis as Haddock, the incredible drunk. Serkis overacts with a glee that brings joy to my bitter, crusty heart. Jamie Bell is very competent as the titular Tintin, and works very well with his sidekick Snowy, played by a dog-shaped wire prop. Daniel Craig just disappeared into the mysterious Sakharine.
As an interesting side note, I forgot several times that this movie was animated.
Now, I have subtly hinted once or twice, but this movie shares its DNA with Raiders of the Lost Ark. The result is a big action movie with truly inventive stunts and effects, which never puts the action in front of the characters. This may or may not make it as a classic, but I had an exceedingly fun time watching this movie, and isn’t that what movies are supposed to do?
