I liked the DLC. It ended up being fun although I was I was at first not very thrilled with the idea of having to fight the same battle over and over again. But then I started demolishing him with new skills and roles and then he transformed... I was thankful for the progression because if there wasn't any I would have been miffed. As for the ending, I am a bit disappointed. I hate to say this but I wish there was some exposition in this game that spells out everything instead of having to piece together info from shards and from character dialogue. I guess I am assuming that Lightning became crystal (and as she informs us) is indestructible and by doing that, keeping Serah's memories and in effect preserving the timeline. She is a remnant in the chaos. It's kind of a cool concept I guess.
