After his suicide, Andy’s ghost (Matt Crabtree) haunts his BFF Stephanie (Pamela Donnelly) in “Biking with Andrew Scott.”

The play has some intriguing elements: A ghost, a tarot card-reading psychologist, karaoke malapropisms and a crazy new religion. Unfortunately, Stephanie’s repetitive histrionics are unpalatable as she blunders through Kübler-Ross’s five stages of grief: denial, anger, bargaining, depression and acceptance.

The cast plays caricatures, not characters. Crabtree, however, is exceptional as an eponymous spirit, and Jason Stuart delivers a fine performance as Chad, Andy’s lover.

There are a lot of little likable moments, especially Karolyn Luna’s madcap substitute tarot card reader, and Alvetta Smith’s mellifluous voice belting out from the choir. Sadly, “Biking with Andrew Scott” is not a thrilling ride.
