LARPing, doom metal, and a soul-eating succubus come together in "Knights of Badassdom," a sometimes plodding, sometimes enjoyable comedy of less-than-epic porportions. Peter Dinklage, Steve Zahn, and Ryan Kwanten mug their way through the film that features a limited story but enough small scale charm to make it passable.
The story revolves around a team of Live Action Roleplaying friends who accidentally unleash a demon during a LARPing tournament. The narrative itself does not generate much energy until film's end, but the characters are appealing enough to makes things watchable. When the team bursts into mock heroism, things really take off.
"Knights of Badassdom" does not have enough Dinklage, and chunks of its story and character beats seem to be missing; but it does mildly satisfy. There are laughs and gore, and the leads are charismatic. This is a very minor comedy, but it supplies a slightly above average amount of fun.
