Some parts of Star Wars never go out of style. Every new project has a cute droid, for instance -- even the deadly serious Andor slipped one into the mix -- while starships and other technologies evolve from previous models earlier in the timeline. The franchise endures its ups and downs in part by adhering to those classic tropes and building Star Wars' identity in the process. Lucasfilm shepherds them very carefully for those reasons, which helps keep its galaxy thematically unified across generations of different projects.
