No man, that specific ending can be made to work. But you need good writers, several more seasons and good taste to do that. Martin gave DandD a finish line, but they had to figure the trail and make the run. They just suck at that so bad that it almost killed their entire careers, got them dropped from the job they had lined up and poisoned everything they touched for 5 years. Netflix just gave them the “3 body problem” adaptation. I'm sure it will be good because the thing is already written, and they are usually good at coloring between the lines. Just not good at coming up with new original or creative stuff.
