Although V for Vendetta wasn't a superhero movie, it was far better than any of WB's other DC offerings. The performances were stellar all around, as were the screenplay and direction.
Of their superhero offerings, I rank Burton's first Batman film highest, followed by Superman II. Believe it or not, Burton's films were considered a fairly dark take on Batman in their day. Burton's Gothic Gotham was enhanced by brilliant production design and cinematography. Burton and Keaton presented us with a Batman who, faced with a ruthless foe who killed without remorse or reason, used every resource at his disposal to defeat him. Batman's willingness to use deadly force along with the Joker's vicious plot made this movie far more realistic, dark and gritty than Nolan's films, at least for me.
