If you loved Broken Blade: The Path of Separation, try Mobile Suit SD Gundam Mk IV
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What they share
Both films are directed by Tetsuro Amino, and they sit in Action / Animation territory. If that's the register that drew you to Broken Blade: The Path of Separation, the second film will land in a comparable space — through a different lens.
What Mobile Suit SD Gundam Mk IV is
It seems someone shrunk the mechs. The SD Gundams compete in a race. Because small robots need vacations too.
