I don't reflexively hate the idea - I just think the timeline is tough
With A Christmas Story, Richie would have been born around 1930 - so putting this with his kids in the 70s makes sense
I just think we are mostly past heavy 70s nostalgia
Now it's us kids on the 80s & 90s who are doing this very thing - taking our kids home to experience a Christmas and Christmas season close to what we grew up with, see family and friends, etc
That bit is very relatable and I think there is a story to be told there - I think the could be a story within there about wanting to see and experience snow and having the weather just not cooperate and then build to a big storm, etc
I just don't think the nostalgia bombs are going to hit as hard in a 70s setting
