They’ve got civilians trapped.
I love that while the avengers fought the aliens you also see them helping to evacuate people so they are safe. It’s not just fighting, it’s rescue as well.
YES THANK YOU! This was my huge and horrible problem with Man of Steel. No help. Buildings falling left and right. I just kept saying “There’s another 10,000 dead people…oooh, and another 10,000 right there!” And no one cared. It left me feeling a bit sick, actually.
