[Full Metal Alchemist: Brotherhood] - 12 & 13
This material is being handled fairly well and I can't really fault the direction but I don't really feel the same emotional connection to the story that I did with the original series.
Is this simply because the original series was fresher? Was it because the original series had the kind of pacing that allowed you to build up a solid connection to the charters or is it all nostalgia that I have for a show that I watched when I was much younger? It's hard to say without revisiting the original material.
I've been rewatching the original series. They just layer on many more character moments in that opening season, so there's a much stronger connection. The whole Nina angle represents a huge tonal shift that's felt more in the original, just because you had more time devoted to her relationship with the boys.
