I'm going to see it tonight as well. No doubt, the first preview will not be a finished product. The trick will be to see the fragmented bits, the moments of brilliance, and try to figure out if it can all be assembled into a hit show. Let's face it, this show will be quite a bit different when it finally reaches opening night.
All of Taymor's shows have moments of visual splendor. Narrative, though, has never been her strong suit. But if the story and characters are interesting and compelling in Spiderman, I think this could be a huge hit. If not, then it's "Across The Universe" again, which had beautiful visuals, but was ultimately a bore because nobody cared about the plot.
Behind the fake tinsel of Broadway is real tinsel.
