Invader

Writer-director Keating knows how to deliver the goods in lean fashion, with “Invader” clocking in at just 70 minutes and ending on a fantastically creepy note of utter dread.

At a raw and rare 70 minutes, Invader is Keating challenging himself to deliver the leanest, sparest home invasion imaginable. But it’s only minimalist in the story and cinematography.

Even though Invader presents some interesting ideas and even a few tense scenes, the movie fails to capture much interest beyond its initial premise.

The best thing about “Invader” is that it’s short. But for much of its 69-minute runtime, it is thoroughly unpleasant, which makes it feel much longer.
