I was going to say "very fleeting" because I seem to recall that show got pulled after only a handful of episodes, but according to wikipedia it actually ran for 4 seasons. I think I only watched it once or twice and it was truly idiotic, even by 80's sitcom standards.
I remember that Small Wonders was on our local channel around dinner time on a Saturday evening after the sports coverage was over and they needed a filler before the local evening news came on.
It reminded me of the type of low quality production that an obnoxious furniture store or used car dealership would pull off.
My Daughter (5-6 yrs old) liked the show.
