Mazinger Z is a series even my mom knows since she used to watch it with me when I was a very little kid. The OP/ED songs sounded oddly familiar, even though I have probably forgotten them from when I was little. I must say, this is great... very good choice in picking up a new show.
That aside, I noticed there were a few missing lines during the episode (as well as a few mistranslations). I was wondering if the noisy audio was a bit distracting in hearing what was being said. I was hoping you guys could check over it a bit more, although I must say there's nothing too important being missed in the dialog... since it's not some philosophical treat. Heh...
Great choice, good work. Carry on!
