D.C. audiences have plenty of opportunities to catch ‘80s “classics” on the big screen—thanks, ubiquitous outdoor summer movie series!—but AFI’s annual “Totally Awesome: Great Films of the 1980s,” now in its sixth iteration, provides a refreshing blend of the commonplace (Spaceballs, Predator) and unheralded classics (Dead Men Don’t Wear Plaid, Ishtar). One of the final selections, Fred Dekker’s The Monster Squad, falls somewhere between the two, an initial box-office dud that has gradually become a touchstone for the Nintendo generation. Unlike most of its contemporaries however, the charm of The Monster Squad has not succumbed to the ravages of time, recalling a nearly forgotten era when vampires were not yet defanged.
