Thoughts

When the games are going down and Sora/Shiro reveal their intelligent planning, it's quite entertaining and definitely worth the watch.

The problem, of course, is that outside of that, there's nothing interesting. Characters don't really get any development beyond "realize how awesome Sora/Shiro are"...
