CBS Cancels 'B Positive' Word is out that CBS has cancelled B Positive after two seasons. The comedy, which wrapped its sophomore run in March, had been seen as on the bubble for renewal. Fellow Chuck Lorre-produced sitcom 'United States of Al' was also cancelled yesterday. Both shows were fairly well-received by critics but failed to draw strong viewership numbers.
The half-hour series stars Thomas Middleditch as Drew, a therapist and recently-divorced dad in need of a kidney. He finds a possible donor in Annaleigh Ashford's Gina, an unsophisticated woman from his past. Together, they form an unlikely friendship and start a journey that will greatly impact both of their lives.
