I almost gave up on this one because it didn't seem very interesting...until the twist revealing Aunt Phoebe had Alzheimer's. Very poignant episode and handled very well, especially by Barbara Rush who portrayed Aunt Phoebe so convincingly.
Also what made this episode meaningful to me was to see the Hawaii Theater as it was back in the 1980s. The theater where Aunt Phoebe in the beginning hides from her imaginary stalker is not in New York. It was the Hawaii Theater. I have lived in Honolulu my entire life so I recognized it and the surrounding shops in the episode. It's so nostalgic seeing all those stores again, almost all of which, of course, have been replaced by new ones over the years.
The Hawaii Theater was delapidated at the time they filmed this episode, but I remembered back in the early 1980s (or late 1970s) going to see cheap movies there and they had a pipe organ that someone played before the movies began. Then, they closed the theater, but later raised money to renovate it and reopened it in the mid-1990s. Today, it looks great and there are regular events and shows. In fact, I saw Neil Sedaka perform there a couple of years ago (he comes every year and performs there at least once while he is in the islands) and also the Chinese Acrobats/Circus.
One question I have about this episode is what was the significance of all the flirty glances and grins between Magnum and the maid? It didn't seem to fit into the storyline, and I kept thinking the maid would somehow play a big part in the plot, or that she would be a recurring character in the show. Not that I am complaining, though!
