That’s one lingering conclusion after seeing a midday matinee of Bob Bartlett‘s gothic horror play Mary Shelley’s Monsters, a moody, meta deconstruction of the author’s trailblazing novel Frankenstein, examining its text, the god complex of its namesake scientist, and, of course, the Monster he creates. The day of our Mary Shelley’s Monsters matinee, the cemetery was anything but deserted, modestly busy with Sunday strollers and dogs happily playing off-leash all over the grounds. An amusing interlude using doll versions of the movie Bride and Monster as puppets is spoiled by the daylight. Through Clark’s insistent portrayal, the play’s conception of Mary Shelley as a genteel Goth girl who’s the true mad scientist, comes into view. Mary Shelley’s Monsters (★★☆☆☆) runs through Oct. 12 inside the Chapel at Historic Congressional Cemetery, 1801 E St.
