>>117160628cym = closure to the diamonds, to the fusions we never got to see, to steven's identity dilemma and mommy issues, to the corrupted gems, to gem homeworld, basically to every main thing in the series
movie = no real closure since its its own contained thing, however gave a bit more closure to the diamonds through spinel's little arc and its ending
future = basically an epilogue, but gave closure to steven's other internal issues, steven and connie's relationship, and further closure for the corrupted gems as well as the crystal gems
