I have the entire series Al, and really enjoy them. You will see a number of TAGS folks in them, including Thelma Lou, Barney, Howard, Millie, and many others.
It's kind of funny also in that you will see some characters just kind of disappear. And you will see Ben's daughters come and go, sometimes with different names. It seems to lack continuity in that regard like TAGS did.
But I think you'll enjoy them. Have you just watched the 1st episode? That was a 2 hour pilot move and Ben's daughter in that one was recast to a different actress. Anyway, the second actress (Lina Purl) in real life is involved romantically with Patrick Duffy (Bobby Ewing on Dallas).
anyway, let me know what you think of them.
