A lot of Game of Thrones fans think that Jon Snow deserved a better ending than what he got in Season 8, but there are some who beg to differ.
Majority of viewers seem to agree that Jon Snow should've gotten the crown. It was, after all, his destiny and he has shown that he is capable of doing so. While to some it seemed like he was shortchanged, it may actually be the total opposite.
He may not be the king of Westeros by the end of it all, but he did have a hand in shaping its future. In a lengthy article on Hollywood Reporter that dives deep into the journey of the character through the years, writer Josh Wigler argues that even though Jon Snow was practically born to sit on the Iron Throne, this wasn't what he wanted.
Game of Thrones Season 8 has given Jon what he truly desired in his heart. He was able to follow his own path as opposed to treading the journey to the destination he was forced to be on. If there is one thing Jon is all about, it is duty. He has always strived to do what is right because he was taught that way.
But suddenly the line between right and wrong was blurry after he kills Daenerys, which he himself can't reconcile as the "right" thing to do.
The real crown he was always meant to have lies on the other side of the Wall. "For a man who knows what death looks like (namely, that it looks like nothing at all), perhaps it's a happy ending after all that he ultimately chooses to disobey orders and instead return to the place where he felt the most alive," Wigler wrote.
Either way, if you are still not convinced, you might find solace in George R.R. Martin's take on the story, which he plans to explore in The Winds of Winter by next year. If not, you might be interested in reading an alternate version of Game of Thrones Season 8 by a talented fan.
