I absolutely agree with you ecchi! Plus the shows were watched on TV screens smaller than our computers back then so they could get away with cheesy props seen on tiny blurry screens compared to what we watch shows on today.
To me it's kinda like watching early Star Trek or Batman TV shows. Take away the fond childhood memories and they really are corny crap compared to what we have available today so I prefer not to watch them now (except for the occasional nostalgia flashback) and just remember them as they were
I did really enjoy "An Adventure In Space And Time" about the making of the first Dr Who and the series.
