Since I recently got concrit on this, and it occurs to me that not many people outside of the fans of such series tend to understand (or particularly care) a lot of the themes behind Magical Girl anime, I thought I'd share
this link to Anime-Myth's synopsis of Wedding Peach.
Of particular interest are her
notes on the series, as they do a far better job of conveying what the heart of the series really is than I ever could.
