Spoiler for Obsolete Signum:
In resume i think Anti-Magic is bad because make any progress a mage can achieve completely meaningless. Even if Cypha have more effective powers, the battle makes clear the gap between her skill and Signum's(Cypha never land a hit on Signum before Laevateinn's destruction). I said Belkan Knights are obsolete by virtue that none of their praised arts and fightstyle will be of any significance against the modern mage-killer warfare triggered by Scaglietti and affirmed by the Huckebein. Just like Knight in real life have nothing to do with modern weapons able to pierce their armors, Belkan Knights are screwed against powers able to nullify their attacks and defenses. They're still strong, just not effective anymore. Seeing the strongest of them falling so quickly behind the Eclipse saddens me greatly.
I finaly came into a bare acceptance of the route Tsuzuki is following here, te evolution of warfare in Nanoha is in constant motion and Signum & the Wolkenritter came from and old era, they were impressive for a time but their era is ages over and that reality is finally catching up to them. Fortunately, my other fav. character, Subaru is a young fighter better suited to fight modern threats and with a fresh mind & technique that allow her to still be able to learn new tricks and adapt to the current exigences of the present day battles. Plus, the hot blooded underdog is a much more flexible character than the Stoic veteran, Signum is stronger than Subaru and has a hella lot more experience but is also more likely at her limit now, she won't get much more stronger than she already is, Subaru on the other hand have plenty of space to grow. I don't mind seeing Subaru trashed because i know she will rise more heroic and boisterous than before, that's what hot blooded heroic types like her do. Stoic Badasses can also be determinators?
Nanoha and Fate being young, modern mages also have nothing to worry, just need to carry a different gun and that's it. ViVid so far is doing a very interesting effort to recover the romantiscism of the strong knights of the past and is one of the main reasons of why i like it.
Nanoha's determination at her 9 years is truly impressive her battle with a demigod like Reinforce is one of the more epics battles on all the franchise(so far is the more Epic Boss Fight Nanoha has battled in the franchise, neither ViVio or Tohma are able to top this battle in my book yet). The debut of Excellion Buster was made of pure win and the second try accompannied by "Snow Rain" in the background made it also a very touching scene. Hope that the movie also make and effort o equal or surpass A's epic soundtrack, the BGM's applied o the Wolkenritter are beautifull and powerfull pieces of music, representing all the glory and tragedy that surrounds them. This movie have a lot to work with and i'm sure they will need to left some things behind, just hopethey made the right election.
