You know how I know yesterday's trailer for The Avengers didn't really set the world on fire? Because I was away from my computer when it went online, and by the time I got back two hours later, nobody on my twitter feed was talking about it. Yes, of course, everyone watched the trailer-- it's the first look at a blockbuster that's been taking shape since the first Iron Man in 2007, and any glimpse at Captain America and Tony Stark picking on each other is worth a look. But once it had been seen, it seemed to fade away instantly, making no more impact than the official images and set photos that we'd been seeing for months. If you barely knew that there was an Avengers movie coming, sure, maybe this was exciting; if you've been following it for months like we have? You might have already forgotten it happened.
