Stood the test of time (no pun intended)
Just got the DVD set, watched 3 of the 4 series over a couple of days, couldn't stop it was so good.
I was amazed that over 35 years later I still remembered most of the plots and characters.
Many shows don't stand up to memory (eg The Tomorrow People now looks laughable) but this one does.
I found myself guiltily attracted to Liz (Cheryl Burfield) and am now relieved to find that she was actually over 18 when this was filmed! Also Beth, her older self, was very fanciable, but the actress hardly seems to have worked again which is a shame.
One error I noticed - Commander Traynor used a light-year as an expression of a long time. He was supposed to be a physicist!
Morgan C Devereaux - just as mad and scary as I remembered.
Dennis Quilley carried the show in my opinion.
