Uh I think the end of Canaan is terrible.
First of all, there weren't enough actions at all 'til the very end. And when I saw this anime, I thought it was going to be action packed.
Secondly, I thought they were finally going to give some insights to Alphard and Canaan's past, instead of the annoying "O HERES WHAT HAPPENED ACCORDING TO MAH MEMORIEZ."
I just can't accept the end at all, I feel like pretty much nothing happened throughout the entire series and it seems like they didn't even really explain what was going on at all. It's almost like reading a really, really, really, really, really, and I mean REALLY long run on sentence, and at the end you just don't understand what you just read.
