It brings me absolutely no joy to report that “Chicken Run: Dawn of the Nugget” is fine. That’s probably more than enough for parents looking for something to keep the kids busy on Netflix next week, but it’s not the standard set by the creative geniuses at Aardman Animation, the stop-motion masters who have gifted the world with Wallace & Gromit and Shaun the Sheep. Even their minor films—like the underrated “Flushed Away” and whimsical “The Pirates! A Band of Misfits”—typically rise above fine. A lack of ambition, just-off comic timing, and inferior world-building keep this bird from flying, despite there being just enough bits that work to make it worth a look, especially if you forget who made it.
