Well, I think it was a really good series, far better than the regular DDP. The plot was brilliantly pesented, and it had very few flaws. I'd give it a 8/10. Of course, you have to approach to it as a kind of "What if..." or "Heroes Reborn" or wathever other example you can find of parallel-non-official story.
Only thing I didn't like was the drawing; quite bad.
