Literally nothing was answered

It was like giving your kids a playhouse, but as soon as they figure out how to interpret the instructions for building it they never touch the thing again. Leaving you $100 in the hole for nothing. Oz found himself, but Oz isn't who I was interested in! What about Alice, Break, Vincent, and the Will of Abyss? They were all intriguing and had promising issues left unattended. The Will of Abyss was my main interest towards the end there (once she's found to be Alice's twin). I was expecting some crazy trip where Oz (and maybe the entire gang) is dragged to the lowest part of the abyss due to his clock, and they resolve what's going on with her and the tensions between her and Alice. Speaking of which, Oz's clock never timed out, nor was it stopped. Why have that entire plot point then? To tease the viewer!? Moreover, what happened 100 years ago? The ending wasn't horrible. I really liked the final smackdown, and Oz's acquired sense of self and dealing with things. I'm just livid because I was into this anime for the mystery, the unknown, the sense that something isn't quite right, and none of those mysteries were solved or answered! I mean wtf is this? I also was into the anime for it's lovable cast. Everyone had an intricate/mysterious backstory, but the ending just revolves around Oz. There isn't a bit of
ending for anyone but him and a little bit for Alice (which is directly linked with Oz), but I digress. A great anime nonetheless, but there has to be some kind of sequel that ties up the loose ends to make it stellar.
