At risk of being a dork I’ll also compare this to Star Trek (largely because OP is a clear fan). Both series are really timeless and impactful imo because they portray people as almost supremely emotionally intelligent. Everyone is very professional when they need to be - capable of great emotional restraint, but also deeply empathetic and caring and ‘tender’ when the time is right.

I mean Gimli is supposed to be the “emotional hothead” of the Fellowship and he’s literally more chill and emotionally controlled than most of the people you run into working retail
