I... Thought I'd have something to say, but words seem to fail me when I try to describe that last episode. Suffice to say, it's probably the only thing that could rival the endgame of Magical Project S as my favourite moment in the magical girl genre. Hell, I was even tempted to replace the Star Sapphire Oath in my sig with those last lines, but then I thought it was maybe too soon and would be an obvious spoiler. >.>
But, um... Oh wow, that was a great series, no doubt~ I'll have to say that my favourite characters ended up being Homura and Madoka herself, as they really both embody the traits that I actually think of when I think "magical girl".
