Whatever comic gems you’re expecting from a cast like this never truly emerge; there’s too much going on, as “The Eternal City” lumbers from broad violence to treacly sentimentality.

This sequel is a superfluous and unnecessary IP extender, which might be okay if it wasn’t creating a problem for parents who have to explain to eight-year-olds why they should not see it.

The film settles into a generic groove that makes it seem at times like a “Spy Kids” movie minus the gizmos (and, therefore, most of the fun).

In the end, one wonders if this sequel was truly necessary. With stronger writing and more impactful punches—both comedic and physical—this spy thriller could have been the riotous affair it intended to be.
