If you like “Marvel’s The Avengers” (there’s almost nothing to dislike; it’s as close as a movie can come to the fantastical reality of a good comic book), stick around for the closing credits. By this point, your grandfather knows to stick around for the scrap of preview awaiting the last disclaimers and thank-yous (the scrap is called an Easter egg). “The Avengers” puts the egg before most of the credits — it just feels like the natural end of the movie.

Yes, getting the egg out of the way gets you out of the theater sooner (the movie runs about 2½ hours). But it also invites honest appreciation for the hundreds and hundreds of technicians who bring off these extravaganzas – the effects and sound people; the folks who devise and design and build the props and costumes; the men and women who helped make the destruction of midtown Manhattan (by your standard cavalcade of shimmering reptilian evil) a ridiculous pleasure. It’s tempting to envy the civilians watching Robert Downey Jr. (Iron Man) and Scarlett Johansson (Black Widow) flying around the neighborhood from a window of their skyscraper, even after the Incredible Hulk barrels past all the cubicles and through the glass. We have 3-D glasses. They’re actually there.
