The kids loved it, 12 bite sized adventures for Asterix and Obelisk on their way to Rome (aka tasks of Hercules). The kids could stop the film, watch their favourites again (and again). However, for an adult, it lacked the classic Asterix feel and felt "bitty". Still, there were all the classic jokes to laugh at, so it was easily watchable.
Before I go on - the synopsis above needs proof reading! It's 50 BC, not "so b.c."!
The recent death of Uderzo, not long after the revival of Asterix's adventures by new writers, prompted me to look at the feature films. I have loved Asterix since I first encountered him as a child, and have been wary of the films in case their characters didn't match those in my imagination.
There is an element of that in this film. The voices don't quite fit with the characters I know, and it's unhelpful that the English lines are often rushed to fit with the original animation. The basic story is fun and quite clever, but the style is very much of its time (the film was made in 1976) and looks rather dated now. Overall it's a good effort, and a reasonable diversion, but not a patch on sitting down with one of the books.
