What WW does have going for it, is name recognition, and that the film will be the origin story of a DC comics character that has been around for more than 60+ years. You think that wouldnt get attention from the general public? Especially with films based on funny books these days being hot properties with Hollywood studios these days.
I think name recognition is a bit overrated. I remember the same arguments being used about Superman Returns and X3. The Returns people claimed Superman's name recognition meant it had more fans and would translate to bigger BO. The X3 people said just because people recognize the name does not mean they are fans or have any interest in the character. Here it looks like the X3 people were right.
Another example more people probably know Mickey Mouse then any comic superhero but if Disney made a new $150 million cgi Mickey Mouse movie they would probably be pissing their money away. People know Mickey Mouse but they have no real interest in the character. People may know WW but I have the feeling most people other than comic fans just consider the character rather lame.
