I think it's pathetic and sad that some people follow a film months before pre-production, watch all the behind-the-scenes footage, analyze every detail of a trailer, and then ***** and moan when their film doesn't measure up to a dozen viewings.
I tip my hat to Jon Favreau and other filmmakers who realize how much they're up against, and strive to top the impossible expectations. They understand a large portion of the target demographic is a bunch of analytical ass-hats, and they move forward anyway. The Comic Con appearances, the viral marketing, the set visits on AICN, it's all a part of coaxing the most cynical of *****es to give a film a chance, because hey, the trailer isn't enough.
In a perfect world, we wouldn't have fanboys, and people would realize that watching a movie TWICE must mean there was something worthwhile about it to merit a second viewing. In a perfect world...
