The opening scene, Hisagi's joke (like a last laugh on the readers), Rukia's promotion... there were all nice things, taken independently. And by drawing this epilogue, the author avoided the Saint Seiya's end I had imagined for Bleach since a few weeks (months even). I just hope this "Gunm-like" conclusion won't be erased in a few years. {looking at the Gunm titles publication history...} No, I really hope it won't.
4/5 because of the content. As a chapter in the manga's continuity, it was pretty unworthy.
4-5/10 probably for the series. (it should have been shorter than Dragon Ball)
I am also surprised that Ichigo didn't take a life-long job there ("to help"). Well, maybe he is working in the medical field on Earth.
The next chapter taking place on Earth would be more inrteresting. After all, 10 years are nothing for shinigami, they live in a very slow world where nothing moves at our pace. For the human characters on the contrary, ten years are a big chunk of life where a lot could happen.
