The ending is satisfying because Marty fixes the immediate timeline while changing what his family believes about itself. George's courage in 1955 reshapes the adult household in 1985, making the time-travel plot a story about confidence and consequence. The final interruption by Doc keeps the adventure moving, but the emotional payoff is seeing Marty return to a family no longer trapped by the same old fears.
