These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Genius Bonus: Those familiar with the record device Alfred tried to use would know why he couldn't work it. It's a professional grade machine, and requires trained experts to use.
One-Scene Wonder: Edgar Kennedy as Sweeney, the detective hired to follow Daphne. At first, he's comical in his effusive praise for Sir Alfred ("Nobody handles Handel the way you handle Handel!"), but then, you realize he too had a wife who cheated on him, and he becomes empathetic. Kennedy is able to effortlessly swing from one mood to the other in the space of a few minutes.
Sequelitis: Or remake-tis, as the remake was criticized as just mediocre, cutting out many elements of the original, such as the second and third music-driven fantasies and how the main character dealt with them.
