LOS ANGELES (AP) ? Alan Thicke's 1980s TV dad credentials were neatly in order on "Growing Pains." His Dr. Jason Seaver was an open-hearted parent and an enlightened husband, working from home to help tend the kids while his wife revived her career. But Thicke's character anchored a sitcom that was also 1950s-retro, part of television's renewed embrace of the traditional nuclear family after a string of single-parent shows.
