It’s great that it’s possible to have all sorts of documentaries on all sorts of subjects for all sorts of audiences, but it’s not so great for the last generation of general-interest movie reviewers. Sometimes I’d rather watch time-lapse footage of mice eating cheese than the docs that get modest theatrical distribution. I’m not specifically referring to Cullen Hoback’s “Monster Camp,” which is okay as far as capturing such endeavors go, but its characters’ immersion in “live-action role-playing,” at a Seattle franchise, donning garb to enact scenarios from World Of Warcraft, is about as far from my fixations as Montrose Avenue is to Missouri. Are the players escaping the dullness of daily life or into another kind of dullness altogether? Sometimes a nerd is a nerd is a nerd… 78m. (Ray Pride)
