Soniku,
This all good and dandy but it's not acceptable storytelling. The world of game of thrones is only interesting as its characters. Is there a point to be made with Jon's death? After being shown he'd grow to be a formidable commander of an human army against the White walkers, having been given the most powerful weapon against them (it has even a name and history behind it) and faithful loyal companions including a giant wolf, I'd expect a major plot development after so much buildup but no... It's all puff.. all back to zero so we can now focus on a different set of characters .. until they die of course... And reset.
