Space Jam: A New Legacy enters the 21st century with LeBron James, impressive visuals, more personal stakes, and a fantastic villain in Don Cheadle. Unfortunately, the movie is too concerned with showcasing Warner Bros.’ biggest franchises that Bugs Bunny and Friends get sidelined in their own movie.

Director Malcolm D. Lee (“Girls Trip,” “The Best Man”) and the credited screenwriters try to wring a little fun out of all this, and miss as often as they hit. But younger kids will eat up the eye candy and get a tiny taste of what The Looney Tunes were all about, even if this big budget monstrosity never comes close to the anarchy created by Chuck Jones, Tex Avery and the team at Warner Brothers’ “Termite Terrace.”

On the whole, I’d go with the 2018 basketball comedy “Uncle Drew” over either “Jams.” One-joke movies, all three. But it helps when the gags don’t stop at the reference point and dribble in place while the clock runs out.

Aside from cast changes and some plot tweaks, there’s not much new to see here. James is an engaging presence, but as this season with the Lakers proved, he alone just isn’t enough.

There’s a nearly astute satire of the app-driven life bubbling under the meta high jinks. And the movie throws so many gags at the screen that several jokes actually stick. But the purposeful sensory overload mostly yields head-spinning stupefaction, leaving a viewer feeling like Wile E. Coyote after hitting a mesa wall.
