In this corner: ''Joan of Arcadia'' (CBS, Fridays, 8 p.m.). In that corner: ''Wonderfalls'' (Fox, Thursdays, 9 p.m.). Here's how to tell these two almost unique shows apart
Joan of Arcadia Joan Girardi (Amber Tamblyn, left) is a smart, cynical young woman confused about what to do with her life.
Wonderfalls Jaye Tyler (Caroline Dhavernas) is a smart, cynical young woman confused about what to do with her life.
The Difference Jaye is a 24-year-old Brown graduate with a degree in philosophy who’s wasting her talents working in a Niagara Falls gift shop; high school student Joan has a few years to go before she can call herself a true slacker.
