Ending isn't everything, for some people. But let me say, the ending wasn't bad, but wasn't very good either. If Isayama had split it into two chapters with 139 being after the battle and 140 being the future. The story might have been smoothed out better. The ending also felt like Isayama wanted to get the story over with. With the anime becoming more and more popular, there is expectancy for the author to be pressured into having a masterpiece kind ending, and this was good.
The manga definitly had high points where I would have given it the 9 or 10, but the ending is what folds the whole story together and finishes it. Therefore, 6/10 is where I grade it. It was not bad, it was just satisfactory with some good elements. The ending is fine, tolerable.
