Yes, I am sure that is my opinion. All his films are grimdark to me. And Watchmen is a book for Superhero haters.
Now the 300 was fun, a hot mess, grimdark, and I liked it.
He sez "I came to comic books through my mother. I loved fantasy art — I love Frank Frazetta…I was into this comic called Heavy Metal magazine>>" which is adultish comics and not superhero at all.
However, just to show you I am not alone:
Zack Snyder Never Really Understood Batman, Or Superman… Snyder’s incredibly eloquent defense certainly doesn’t clarify his creative decision, other than the fact that Snyder thinks the idea of a crimefighter who never kills people is ridiculous. Which it is, as is the concept of a billionaire in a bat costume.
What Snyder seems to be saying is, there are no real heroes. Something along the lines of what his previous superhero film, Watchmen , was all about. Watchmen , however, was a clever deconstruction of the superhero genre; it was a strange move to try something similar with archetypal characters like Superman and Batman.
