I don't know the anime this is based on, but having another fight almost immediately after the previous one ended almost solely for the sake of a contrived fight--and it [i]would[/i] be contrived, seeing as it's a city with 100,000,000 people in and pretty damn big, so circumstances aren't forcing it--is tiring because it gets in the way of getting to work out what the plot is. The previous fights served a purpose by introducing the soldiers, but another long fight right now would just be gratuitous. And unlike anime, we can't cover it with good animation.
