Nope. Honestly, I like where superhero films are right now in terms of seriousness. Several films are very serious (Batman V Superman, Logan) some films are moderately serious (Almost anything by Marvel Studios), and we got some not serious movies (Deadpool, GOTG)
Also, change the thread's name to "Why So Serious?" please.
Agree.
I'm surprised no one has yet mentioned Watchmen. Now there was one helluva serious movie. I think it's one of the most fascinating superhero movies made yet, particularly so because the plot and dialogue adhered so closely to the original comic book, and most of the changes that were made were excellent changes, making the movie even better than the book(s) it was based on.
