I really don't know enough about the groups to comment one way or the other, but they're all just doing it for fun and fandom, so I tend to cut them a lot of slack.
*** ep 47 spoilers ***
Haven't seen 48 yet, but I thought 47 was good. Not a lot actually happened, but it was nicely dramatic. I thought the voice actors did a really good job with this one, especially Tenma's. Made the episode, really.
