I don’t think I have any other facts that are very interesting, but then again I didn’t think not having seen BTTF was all that interesting either. For the record I was familiar with 1.21GW and what it related to… I don’t live under a rock!
I know movie nights are not a thing every family does but I'd imagine having one day modern movie, one day oldish from 80-90a, another day a classic from the 40s, etc.
Wouldn't that have worked if you started from when they were young?
I'm just thinking as that is my plan for when/it I have kids: mix older media with new one and just enjoy it with them. If it is truly good and not just nostalgia, they should be enjoyable even as a rewatch.
Like The Princess Bride or Labyrinth, BTTF currently remains a phenomenom of the 80's and 90's -- familiar to most from that time and deeply treasured by some, but not refreshed and sustained the way the Star Wars, Star Trek, Marvel/DC, etc brands have been.
