After so many mishandled or abandoned series — from “Fantastic Beasts” to “Narnia” to “Percy Jackson” — it’s nice to see one that’s heading in the right direction.

Until Ghostbusters decides if it wants to throw its lot in with one era or the other, it’s always going to be between two worlds. And that purgatory makes for a middling experience that doesn’t quite satisfy.

This newest franchise entry is built on nostalgia and a stacked cast, but not enough to make it worth watching.

The property’s reliance on nostalgia, combined with a lack of fresh narrative ideas or jokes, make ‘Frozen Empire’ a tedious, enervating sit.
