Puppetry and epic-tragedy. Sadly, the two just don't mesh.
Puppets, by nature, make people laugh. They are absurd renditions of reality that ask us to smile and forget about the real world for a while. They are Punch and Judy and children's theatre. To make us cry, give us chills and beg our sympathy, a puppeteer jumps through many hoops for their audience.
The Old Trout Puppet Workshop dangles halfway through the first hoop with their rendition of Beowulf: A Viking Puppet Opera.
