This has been a major source of discourse since the second Nolan Batman film and has only become more prominent since the Matt Reeves movie, with fans taking particular offense at the idea that Robin may not be featured and none of the villains will have superpowers.
What I don't understand is why fans act like these movies are the only Batman adaptations we're getting. The various video games, animated series and films contain the colorful elements from the comics they prefer. Why is it an issue that a handful of live action films take a more grounded approach?
