Today it’s nostalgia. We are going to see the new Asterix and the Vikings film/cartoon. Already from the trailer I can see that they have not slavishly followed the book but that doesn’t matter. The series by Uderzo and Goscinny of the adventures of the Gauls surrounded by Romans has been a central part of growing up. The Gauls have also appeared occaisionally in my lectures.
The adventures of Asterix appear in 33 main books (one of which is a compendium of short stories) and a complete set is a natural goal for the collector. Wikipedia has a lengthy background on the importance and popularity of the series.
