The effectiveness of the military.
I have to say, while I have seen a good number of Kaiju films in my life, I cannot think of any of them from Japan where the military was more effective than they are in War of the Gargantuas.
Were ther any other Toho films where a monster got it's butt kicked as much as Gaira did in this film?
I mean, if the Brown Gargantua (Sanda) had not shown up, they would have killed him.
