‘St. Nicholas’ at Goodman: Drama critic meets vampires. Seriously. He’s bloody amazed, too.

Review: It turns out vampires are real. Who knew? Anyway, the veracity of vampires is the central proposition of Conor McPherson’s one-man play “St. Nicholas,” now meandering across the boards at Goodman Theatre. I suspect the greatest allure of this dubious enterprise, brought to Chicago by London’s Donmar Warehouse, is the presence of Brendan Coyle – yes, the same Mr. Bates of “Downton Abbey” – as the nameless monologist. ★★
