Finally finished this, and now I'm actually happy I did. All because of that one "onii-san!".
I wasn't expecting much from this repetition party. So, even if the ending was hardly innovative and very much bowing to the textbook with everybody alive and happy, I didn't pay overly much attention to it. Or the fact there seemed to be limited causality and continuity in the show, which made it somewhat burdensome to watch, with everything feeling so scripted. Can't say the last battle would have been made any better because of that either. Instead of having Naraku as the big bad boss, it was the jewel. Inanimate objects always make so intriguing and stimulating enemies...
But that one "onii-san!" I already mentioned. It made it all better. Of course I was a Sesshoumaru fan to begin with and that boosted the fun factor of the scene up. As if Kagome after all this time hadn't known what that proud demon would think of some human girl calling him a big brother. Jolly good.
To be faithful to the story, Sango can't help but be in that state considering what manner of a playboy Miroku is. No contraceptives in the sengoku era, either. Maybe she will make Kagome fetch some from the future once she gets bored of being pregnant.
