“The Last Apartment” (*1/2 out of four) was an artless horror melodrama about a yuppie couple (Anthony DiCarlo and Essin Varran) who move to a new apartment in the city where they are overtaken by a sinister force that splits them apart and turns them violently against one another. Amateurish movie is more-or-less a rip-off of “The Devil’s Advocate” and “Amityville Horror” but lacks the scares and spectacle of both. Even at only 83 minutes, you may not “last” till the end of this time waster.
