Although this didn't last a long time, I enjoyed this show as a kid. It didn't have the magic that Three's Company had, but there was something nice about see nice-guy Jack finally settle down with someone. And Vicky was hot! EZ was hilarious and I remember talking to friends Wednesday morning at the bus-stop about this show.
John Ritter was a comedic legend and although this was a bomb, there was no way ABC wouldn't take advantage of Jack Tripper for one more year especially with all the Emmys that John Ritter earned.
Most of this is going off of memory since I can never find it in reruns or even on a DVD. It probably wouldn't be a successful DVD release, but geez, I would get it.
