Review by Mushino

This sci-fi anime throws up many quantum physics/mechanics concepts and if I hadn't watched it through fan subs with easy to understand footnotes, I would have been really lost in my understanding of the overall setting of this show.

I would have enjoyed this anime more if I could understand the quantum science explanations (I still don't after watching it again), but there is one thing I'm very sure about this show and would like to say to those thinking of watching this anime: the ending is quite satisfying for me. There is no cliff-hanger or anti-climax. The ending has a kind of heartwarming and peaceful feel to it.
