Even though the ballad is but a legend, this puppet movie is a greater period piece than most live action medieval-movies.
The authentic costumes and characters really add to the sad tale...
On the sound side it is truly incredible, with well known voice actors giving it their all, and a truly memorable music experience.
The movie's runtime isn't that long, but a lot happens in the short timespan, and with a solid pacing nothing really feels rushed, although i would have loved to see more of Holger's journies through early medieval Europe.
This is considered a childrens movie in Denmark, but there's kind of another standard here than most of the world. So if you don't want your child to see people getting hanged or split in half, you better watch it without them.
If you're a history teacher and want to show your pupils something from the early medieval period, this movie is the one.
