Review of The House Without a Christmas Tree

I have to admit, I was too young to get a lot of the nuances when I saw this, when it first aired back in the 'seventies. I'd love to see it again, as well as the two other Gail Rock adaptations for CBS' "Hallmark Hall of Fame." I do remember thinking at the time that all three dramas rang true... unlike so many family dramas/sitcoms of that time (or now, for that matter).
