I saw the series + first OAV, I didn't get the second because I was really confused and disappointed... I tried to read and learn about the series as much as I could but I still had a hard time following.

In the end I gave up in disappointment. If only I had seen that last video I guess! Still, I feel like it's too much trouble to bother.

I appreciate parts of it and the fact that the series is kind of an enigma but... my head hurts. I need to get some sleep.
