I love The Batman, but it's by no means an original or fresh movie. The Sev7n and Zodiac similarities couldn't be more obvious even if they tried to hide it. Mix that with a little of Chinatown, and you got the movie.
I'm not saying it's good or bad, most comic book movies steal from other movies. But taking from other movies is not something as bad as people say, or even illegal. If that was the case, Tarantino should be in jail.
The Batman is still an amazing movie.
