Director Jon M. Chu has a lighter touch than “Now You See Me” director Louis Leterrier. The latter’s “Transporter” pedigree made sure there was plenty of rugged action, but Chu’s résumé boasts “Jem and the Holograms,” “G.I. Joe: Retaliation,” and more than one film in the “Step Up” franchise. The man knows his cartoons, and that’s a good thing.

Now You See Me 2 is more like a giddy piece of cheese from the ’80s, a chance to spend two more hours with characters we like, doing variations on the things that made us like them in the first place. The revisit, in this case, is well-earned.

Jon M. Chu (several Step Up movies) has taken over directing duties from Louis Leterrier, and he has a lighter, goofier touch. He seems to get that the silliness is baked in.

Now You See Me 2 gets giddy on its own unreality. That sense of freewheeling excess extends from the chip heist — set in a metal-free clean room — to the nonstop contrivances and coincidences to the cast.

Compared with the first film, this one embraces the premise’s essential preposterousness, although not necessarily to winning effect.
