Obviously, tastes vary, but the nostalgia crack part of the show is fairly minor compared to the actual story. It’s really there more to establish that it is set in the past and give a quick handwave to character background.

It gets used less after the first episode or two of each season, which do tend to be a bit more focused on set-up and “vibe” building to some degree or another each season.

There’s no guarantee you’d like it, but the first episode of the first season isn’t really a good example of the show as a whole, nor are the first episodes of each season. Imo, they tend to be a way to let both established audience and new viewers “settle in” rather than being integral to the overall plot arcs. They do tend to serve as character updates (after season one where they serve to establish characters) though, so skipping them entirely wouldn’t be ideal. It is doable though.

Which only matters if you’re remotely interested in watching it at all
