I've been watching the episodes in order, and this is the most enjoyable one yet. Great retro things like Joey Travolta playing a rock star. Check out the early-80s kids in line! High-school-age cousin Diane is introduced - what a cutie! The Simons' friend Gordie, a toy/hobby-store manager, is interesting - hope he comes back later. The crime caper here is pretty good, as these series go. And Morgan Woodward is a great villain. (I'm not familiar with him, but apparently he had quite a career.) Yes, the best of the first 7 episodes.
(Note that the opening credits list "Morgan Woodard" missing a "w" - how did that typo slip by???)
