I enjoyed this episode until the end, which I felt was a serious cheat dramatically. \"Raises more questions than it answers\" is putting it very mildly...In fact, the episode answers no questions at all. Why did the old lady keep reappearing, and why did she have no memory of the couple each time? Why did she shoot at them? Why did the phone work once and not the second time? Why did she hear her father replying, but the father never seems to receive the call? Etc., etc., etc. This is an undercooked script, one that really needed to be sent back for revisions. But it has a nice flair throughout, and it certainly holds interest in its Twilight Zone-style way. The performances are solid. An enjoyable episode overall, but, for me, a frustrating one.
