Although “The In Between” does run on too long, its gem of a script and charismatic actors keeps you fully invested in it and its hard-to-swallow premise.

It’s hard to imagine its target audience complaining over such modest, forgettable slumber-party fodder.

This maudlin, muddled supernatural love story is never boring, even as it frequently doesn’t make a lick of sense.

A sappy but strangely moving YA romance.
