NEW 'SHAZAM!' HAS MORE EVERYTHING BUT LESS CHARM

Sequels, by nature, are more. Whatever the original had, just add more, the rule seems to be. Even more words in the title — how often is a sequel’s title shorter than the original?

And so, exactly four years after the original DC superhero pic “Shazam!” surprised with its clever blend of innocence and silliness, and enough wit to blunt the inevitable ridiculousness of plot, we have “Shazam! Fury of the Gods.” It brings five times the title wordage, more action, more villains, more monsters and more star wattage — Oscar winner Helen Mirren, for example.

But not more charm. The sequel, again directed by David F. Sandberg, feels less breezily funny, less fresh, less fleet of foot. (At two hours and 10 minutes, it’s actually two minutes shorter than the original, but doesn’t feel shorter).

In its favor, though, are some elements that lent the original its pleasures, especially Zachary Levi and his goofy efforts (if perhaps more frenetic) to play a youngster in an adult superhero body, and Jack Dylan Grazer as fast-talking, always-thinking best bud (and foster brother) Freddy — this time given a love interest in appealing Rachel Zegler. It also smartly drops colorless villain Dr. Thaddeus Sivana, who’s apparently still in that lonely cell.

First, a plot refresher. We’re back in Philadelphia with teen hero Billy Batson (Asher Angel), the foster kid who was bestowed in the original with magic powers by a wizard (Djimon Hounsou) and learned that the word “Shazam!” turned him into a strapping superhero (Levi). But now, his foster fam (well, just the siblings) has joined the superhero biz.

It’s not going great, though. The group is known in the City of Brotherly Love as the “Philadelphia Fiascoes,” because of frequent youthful mistakes. We know teenagers have only partly developed brains, right? No matter how many buses or train cars they can hold with one arm.
