I've been watching it on and off. I thought it was actually pretty good considering I knew practically nothing about the show when I first saw it. I wish there was a bit more explanation to where Ginjiro got his magical unlocking abilities, but then again the show revels in the fact that they aren't bothering with things like realism or chronological sense half the time.
It seems like they had just wrapped up enough plot for 19-20 episodes and then realized they still had 5-6 left to go, so it's kind of overstaying its welcome with filler jokes that are hit-or-miss. Should I just skip to the last episode or is there anything interesting in the last batch of episodes?
Eh, the episodes after the Darkest Hour ended were like the ones in the beginning- they're not as easy-going or plot-heavy. You must realize, though, that Sora still has to get back to the moon, so of course we're in for a good climax.

Oh Edo Rocket
Do we have a discussion thread for this? FU Nimation is currently airing it, and has it on sale.
