I am not a Sabaton fan, so I saw this movie without knowing their music. They are a heavy metal band that focuses much of their music on war themes (primarily WWI) with a patriotic/nationalistic flair. Much of it is based on the ordeal of soldiers as heroes. The band was jovial while performing seriously hard rock music. It was very easy to enjoy the music being played. The movie is a full concert filmed in Amsterdam. It was very well filmed and edited to enhance the show's drama capturing the energy of the band members as well as the exuberance of the audience. The camera never rests on one view for more than 5 seconds giving the viewer a lot of visual stimulation while capturing the best aspects of the performance. As someone who was exposed to their music for the first time viewing this film, I can say it was very enjoyable to watch. I would assume any existing fan would find it to be amazing.
