I think if you've watched this show enough since season 6 and have paid attention to any of the production work going on around the final season, you'll be able to piece together the broad strokes of what's left to do. The first episode will be full of reunions and character-based interactions; the second episode will be more chatting at Winterfell and preparing for a big battle; episode three will be a big battle, which the Living will lose so they'll have to retreat southwards; the fourth episode will focus on getting everyone to King's Landing for the final battle; episode five will be the final battle in King's Landing and somehow Westeros will be saved; episode six will deal with the aftermath and deciding who's king/queen when it's all over. What's going to be rewarding, though, is how the finer details inside the broad plot strokes are going piece everything together. We know there are going to be big battles but we don't know which characters are going to die in the fighting; we know characters are going to be meeting for the first time ever (or for the first time in a while) but we have no idea how they're going to behave; we know the Night King is somehow going to be defeated but we don't know the specifics; we know dragons are going to scuffle in the sky but we haven't seen how epic they could make it on screen; we know Jon is going to find out he's a Targaryen but we don't know how he'll react to the news. Intrigue and politicking on Game of Thrones died with 'Hardhome' - since then it's been about getting us to the point where dragons battle ice zombies to save the world, and there's no reason why that can't be hugely, hugely rewarding and exciting.
