According to the new Thor movie, every few millennia the universes line up for an anything-goes cosmic cross-over called the Convergence. Inhabitants of unrelated realms get sucked through portals and tossed together to defy the laws of physics. It happened for the first time in 2012. They called it The Avengers.  Superheroes from all the Marvelverses were plucked from their disparate origin worlds to converge in a single, box office-defying blockbuster.

Physicists predict the next Convergence will occur in 2015—not once, but twice! Not only will The Avengers 2 draw the sequel-spinning franchises of Thor, Iron Man, and Captain America together again, but Warner Brothers’ Batman vs. Superman has Gotham and Metropolis on a collision course—with Paradise Island and Starling City and other DC planets to be swept into the same Justice League gravity pit.

But which Convergence will come to define all of superhero reality?

In Thor: the Dark World, an evil dark elf wants to use the Convergence to remake reality in his own dark image. He’s played by former Doctor Who Christopher Eccleston, but his real name is Christopher Nolan. The Dark Knight trilogy and the gray tones it casts over Man of Steel now define the DC brand. It’s a humorless void happier with the droning rumble of Christian Bale’s Bat-rasp than the giggles of a live audience.

The Dark Knight Elf wants to crush the world into a Black Hole. But Thor, with his lightning bolts and deadpan timing, is all about levity. He’s super-hunk Chris (not Christopher) Hemsworth in the credits, but his real name is Joss Whedon. The Asgardian—like his buddies Tony Stark, Bruce Banner, and even the ever earnest Steve Rodgers—is a Comedian. He throws that mighty hammer at all kinds of monstrous bad-asses, but he it’s our funny bone he keeps hitting. I didn’t see Joshing Joss’ name in the credits, but I hear Mr. Whedon was responsible for major rewrites and reshoots—all part of his uber-duties as the overseeing Odin of the Marvelverses. He’s Captain Convergence, and he wants the world to end in a laugh not a rasp.

Of course the Whedonverse isn’t a flawless reality. There’s a moment in Thor 2 when a funeral barge sails over an Asgardian waterfall and hangs there a moment before dropping—a little like Wile E. Coyote after sprinting past the edge of a canyon. It would be pointless to criticize a Road Runner cartoon for its failure to follow basic laws of physics. And the same is true of Thor: the Dark World and the laws of plotting. The word “convenient” comes to mind, as does “inexplicable” and “far-fetched.” Director Alan Taylor is hoping we’ll be too busy enjoying ourselves to ask annoying questions like “How is it that a random convergence portal just happened to drop Thor’s girlfriend of all people into the exact spot where the Dark Elf’s reality-destroying superweapon has been hidden for millennia?” Comic worlds tend to cut corners. Do we really need to hear a ponderous explanation? Nolanland has plenty of those, and its’ still pockmarked with its own plot portals.

The Whedonverse—despite Whedon having literally majored in Women’s Studies—also can’t find much for Natalie Portman to do but look lovelorn and occasionally panic-stricken. This might be the result of the gender-challenged fabric of superhero reality, since DC can’t even turn a Wonder Woman screenplay penned by Joss Whedon into an actual movie. Apparently Hollywood executives think fanboys won’t buy tickets to see scantily-clad women in fight scenes. And yet the shirtless beefcake shot (Hemsworth provides a couple screamers) has become a staple of the genre (the clothing-challenged Stephen Amell flexes weekly on the CW’s Arrow).

This may or may not be why my wife surprised us both by saying she wanted to see the new Thor movie. I was so underwhelmed by the first that I was going to pass, but I’m glad she suggested it. I like dumb fun. I also like smart fun, but that combination has yet to Converge on a superhero universe. I’m hoping it won’t take a millennia.
