There’s nothing like the ooze of blood to usher in the holiday season. And by holiday season, I mean Halloween, which suddenly seems to be more reverently and feverishly celebrated than Thanksgiving.While some theater companies rely on A Christmas Carol to boost their holiday box office, San Francisco’s Thrillpeddlers rely on blood, gore and cheap thrills. Who needs Scrooge when you have dismembered body parts?Shocktoberfest!! the “annual pageant of terror and titillation, has returned with three one-acts: one new, one old and one old newly updated. The plays are performed in the classic Grand Guignol style, which is to say anything goes on stage, and by anything, I mean in the blood and sex departments.Dubbed Kiss of Blood, this year’s edition – the 11th – is silly, trashy, gory and a lot of fun. Watching these three one-acts offers the same kind of pleasures you might experience watching a trashy/terrific horror movie from the early 1970s.
