I don't get why people hate the ending so much. I personally like the ending. An "endless loop" or "restart of the game" would have been to obvious and stupid of an ending. Honestly, the whole manga gets based off of an endless loop of Yuno trying to get together with Yuki, and then just have the manga keep going in this sad little circle? That's quite lame.
It's good that they were able to bring about an end to the loop. To put this in perspective, this manga is somewhat like Donny Darko (The Movie) in the mulitple universe/endless loop way. Donnie has to find a way to end the time loop, and he does. The movie would have blown ass if they ended it with him not being successful.
Similarly, this manga would have blown ass if they had done something as lazy as just keep the game/sad endless loop going.
Avalongus, as for Yuno's past, the Death God Yuno who was about to kill Regular Yuno went back in time at the wrong time. We never got to see the mistreatment because Death God Yuno went to far back in time, she even says this. The Mistreatment would have happened later in time.
The fact that people are saying that the manga sucks after "Akise dies" or "everyone dies" etc, just proves how good this manga is. It proves that the writer was able to get everyone deeply involved in the manga emotionally. I too like the character of Akise and of course it's sad that Yuki's friends all die and that all the diary holders (well, some) die. But it was done in a good way that benefited the story.
We can't have everything be happy all the time or even most of the time. This wasn't marketed as a happy boy manga :) (Ironic though it is that it's placed in the genre of Shounen, even though it's as violent as it is)
