IIRC it was on BBC2 at around 6pm-ish. I think I was in my last years of High School when I remember seeing it (maybe '92-'93ish) as my dad would always want to watch the 6pm BBC1 news so, after I'd finished my homework, I had to pop around to my next-door neighbours as they had 4 kids who all watched it.
As for the "new" potential version, whilst I understand this is based more on realism, everything in that trailer is missing the innocence that the original had. Maybe this "everything has to be dark and gritty" epidemic in TV/Cinema we've had over the past decade is just starting to wear thin for me but I know I'm getting sick of watching comedy reboots become dire laughter-vacuums really quickly now. There's no "hope", no "light", nothing to inspire anymore, it's all becoming nihilistic negative rubbish and thats just not who I am, nor is it what I want to be bombarded by 24/7, especially not out of context like this seems to be.
