I certainly hope the excellent writing of the show, will allow it to have a timeless element to it (which is kinda the theme of the show, if you think about it). As a Gen X’er, I imagine some things will go over younger heads (the “Odd Couple” references in “I Robot” may not be truly appreciated, for example). Also, some eps were creatures of their time - “Three Hundred Big Boys” was inspired by the GW Bush tax rebate, for example. I doubt that little tidbit will be remembered.
One thing I wonder, will the history of the show itself - the expected cancellations, multiple “series finale” eps, FOX’s juggling of the broadcast order - be remembered?
I know the feeling. I just started watching Stranger Things at the start of the year. I paused after the first two seasons, because I didn't want to just tear through the everything., and because Yellowjackets S2 was about to start. Now that YJ is done, I find myself a bit hesitant to start S3 of ST.
