Summer’s Must-See Movies

THE SUMMER movie season commences today with “The Avengers,” a giant Thor-gasm of Marvel superheroes wrapped in one package. It has the star attractions — Iron Man, Thor, Captain America — from previous summer hits, and magnanimously gives The Hulk yet another chance to make his blockbuster bones. For good measure, it also offers Hawkeye, Black Widow, Nick Fury, a night-of-a-thousand-stars cast, a $220 million budget, and geek-guru director Joss Whedon.
