WB is lost? That depends on what "lost" means.
Do you mean that the company simply doesn't know how to make superhero movies?
That WB hasn't made many superhero movies?
That WB's superhero movies are poor in quality?
First, we have not "only gotten Batman and Superman movies" from WB. In the last few years, we've gotten THE MATRIX movies (which may as well be a superhero movie), CONSTANTINE, 300, SUPERMAN RETURNS, two Batman movies, and now WATCHMEN. All of these are comic book films. There has also been a long-running live-action series based on the Superman mythos as well as various animated shows.
Would we all like to see more superhero franchises? Sure, but it's just not as simple as that. WB is a business, and they must run themselves like a business. That means giving attention to several genres, not just superheroes. When looking at the quantity coming from WB, taking "other franchises" into account is a valid argument. Some of you seem to insist to look at WB in terms of it's superhero potential, or what you think it "should" be doing. But WB is not a studio that can simply dedicate itself to making just superhero movies. It has many genres it must cover, and other franchises to deal with. So the fact that WB does not make a ton of superhero movies at any given time should really be taken in context.
It's difficult to compare Marvel on the same level, because Marvel, until very recently, was not a studio, it was a comic book company who sold its rights to other studios. Namely FOX, SONY, and LION'S GATE. Marvel has its own studio now. We'll see how IRON MAN and THE INCREDIBLE HULK do.
Now yes, Marvel Studios was created for the express purpose of making solo films and new franchises, but we have yet to see the quality of their work. IRON MAN looks solid, but THE INCREDIBLE HULK could go either way.
It's interesting. No one *****es that IRON MAN took years and years to develop, but if THE FLASH doesn't materialize right away and GREEN LANTERN doesn't show up a year after it's had a director semi-attached, it's "WB is lost".
