U.S. cable network HBO has decided not to order second seasons of its sitcoms "Hello Ladies" and "Family Tree," EW.com reported Thursday. The shows earned good reviews from critics, but did not build large enough audiences to justify renewal, the report said. "Hello Ladies" starred comedian-writer Stephen Merchant as a socially awkward Brit looking for love in Los Angeles. "Family Tree" starred Chris O'Dowd as a man digging into his family history.
