Second 'Avengers' trailer hits the web

The second official trailer for "The Avengers," probably the most anticipated movie summer, was posted online today.

"We're not a team, we're a ticking time bomb," Mark Ruffalo's The Hulk/Bruce Banner says at one point. It's an apt description for our biggest fear about this movie. With so many personalities and characters jockeying for screen space, will there be time for a cohesive narrative? We have total faith in writer/director Joss Whedon, but little faith in the studio system that has come to see superhero movies not as one entity but a jumping off point for sequels. 

"The Avengers" is scheduled to hit theaters May 4. What do you think? Will you spend your dollars on this pretty cast of super-men (and woman)? Or are you heroed out?
