Tsk, Tsk. Now this is a lazy, poorly-written episode with several things wrong with it. As an earlier reviewer pointed out, the father character comes out with a ridiculously corny line when he decides to get his physicist friend involved. Not to mention the fact that this is virtually his first recourse. He doesn't even check the little girl's wardrobe to see if she's hiding in there. Had I been in his shoes, I'd have searched every nook and cranny of the house first before even thinking of bringing anyone else in.
Then there's the matter of this physicist. Now, this episode screened in 1962. The physicist's conception of what the fourth dimension is or could be seemed to be damnably vague. Are we really expected to believe that a scientist in 1962 would be unaware of Einstein's generally-accepted theory that TIME is the fourth dimension? Is he, perhaps, supposed to be a physicist who disputes this theory? The fourth dimension bandied about in this story doesn't seem to have anything to do with time-shifting.
I also have to agree with the other poster who cited Sarah Marshall's overacting in the role of the distraught mother. She submits a performance hammy enough to feed a family of four for a month.
Give this story a miss. If you have anything resembling a logical mind, the problems with the episode will probably result in a degree of irritation that outweighs any entertainment value. The dog's cute, I suppose. :Pmoreless
