I guess I must be the only one who honestly never really noticed any reused battle footage in the finale. Maybe it's because I don't really care for battle scenes in general to begin with. And to be honest, even with
the knowledge that there are in fact reused shots, they don't really bother me at all. I guess I'm just wired differently.
As for the finale itself; it's not bad, but I was never a big fan of it. I don't know why, but somehow it feels disconnected.
