What makes Star Wars so entertaining?

Yeah, uniqueness is one.
But they do a great job at immersing you in the universe.
Makes you attached to their world (more like galaxy), even if it can be a bit shit at times.

It just hits me with waves of nostalgia.

So much so that when I saw this irl, made me tear up. But also be in awe of the show.
