Hrm ... well, I guess I kinda liked ep 2. I guess it is fair to admit that I am not much of a mecha fan to begin with in general, but somehow the contrast of Madoka's cheerful, genki personality and actions in the middle of "serious mecha drama story" is the most interesting part thus far. The relationship between Madoka and the robot reminds me of that of the main character and her robot Zero from Skygirls for some odd reason....
I must admit that I giggled when I heard the VA of Muginami - isn't it the same who VA's Menma from Ano Hana? Somehow the contrast of Menma with Muginami was ... odd. Also Lan's "Wan." statement also made me chuckle.
7/10 vote from me for ep 2.
Hrm ... well I guess I will keep watching for the moment.
