This show died not because the subject matter was too controversial, but because the show sucked.
Plot lines included the happy couple buying a waterbed, then trying it out while the parents are hanging out in the room below -- it bursts of course, and oh what comedy ensues! You can imagine.
As for making David Birney a star -- well, that depends on your definition of star. I guess for Ozzie Nelson this was daring material, and maybe if you were in Kansas, but as a New Yorker, the idea of a kindly hip Reform Jewish family watching their son marrying the daughter of a somewhat uptight but ultimately kindly well-to-do Irish Catholic family didn't exactly set fire to the aerial.
