It's not like another typical superhero movie, where the protagonist and anti-protagonist got the superpower and all of sudden they start doing their heroic and villainous motivated work. Here the hero is a common man, where you see how common thinking he has. He is not self-less from the start. He doesn't show any kindness towards anything, he thinks of himself first. You also first do not see him as a hero. The same goes for the main villain as well. His side is also been portrait very well. You'll find pity for the villain also. You'll be told about the villain and hero from the start of the movie. But the plot is nice, the character development is good for both. Some part you'll feel is missing or just showcased without any explanations, but yeah it will not affect the movie too much. Again it will give you a different type of experience about the superhero movie.
