Wasted potential could be the most apt description of this one. An intriguing horror premise of time travel as karmic retribution is undermined by some weak acting and plot holes. The first act is excruciating, as the leads awkwardly fake-laugh their way through painfully unfunny dialogue. The second act is the protracted process of the leads taking fifteen minutes to realize what's immediately obvious to the listener. By then there just isn't enough time remaining to build the tension and dread the story's aiming for, and we still barely know a thing about the leads or their historic counterparts. A nice idea, badly executed.
