Re: David S. Goyer IS the Script Writer! - Part 2
That raises an interesting question, then. Is it permanent? Because, we see that Superman perseveres against the gravity beam and atmosphere emitted from the World Engine. The movie certainly implied that Superman exhausted his sunlight reserves to pull off what he did. Suggesting that it would be futile.
I would rather Batman concoct something like Red Sun frequency if he was to go to that extent to weaken Superman. Again, how Batman counters depends on how detailed the research on Kryptonians/Superman are.
