You fanbois realize that you're not the audience for this, right? Do you think the producers are going to make their money back from comic book fans?
It's a Broadway musical, first & foremost. The source material is incidental - it's just an excuse to stage spectacle. I'm no fan of Taymor's films - she is squarely a theatrical director and doesn't know how to scale back for the screen - but they hired her for the job because she has a track record for creating extravagent, money-making fluff (e.g., the Lion King stage production).
As for these pictures - they're so photoshopped & post-processed, it's impossible to see whether the costumes will look cool or absurd when seen in person. But one things for certain - a "faithful" recreation of Spider-Man outfits would looks stupid for a Broadway production; you're basically going for Kabuki for something like that, so it's got to be over the top.
