With Bad Doc still unsure about betraying Edna Strickland, Marty must help young Emmett complete his real demonstration at the Hill Valley science expo. But after his success the entire town mysteriously vanishes.
The story in this episode is much, much better and really does come together well. There are long character scenes which work perfectly, giving the story some soul, and the climax feels like you're actually taking part in a BTTF adventure.
Michael J. Fox even voices William McFly (who we've seen peeing on Marty) and several older Martys who all appear at once. Overall, it's a satisfying 'conclusion' to a long journey, but I feel there are still plenty more adventures in store for Marty and Doc in the future...or the past...on an alternate present.
