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.
Big Lipped Alligator Moment: During the live-action film, the villain suddenly appears at one point, singing a song with his henchmen accompanying on violins. Cutey Honey's facial expression at that point has become slightly memetic.
Re: Cutey Honey deserves special mention. Natsuko and Honey have two instances of Intimate Healing that involve naked cuddling and French kissing respectively, in addition to assorted other moments of Les Yay, and at the end of the last episode, Sister Jill ends up floating naked in a void and possessively hugging an equally naked (and unconscious!) Honey.
Periphery Demographic: Go Nagai says he was surprised when he found out that the series attracted so many female fans. Hence, the creation of Cutey Honey Flash.
"Weird Al" Effect: How many people have even heard of Tarao Bannai? That was the source for Honey's "Sometimes I'm a..." speech, which is now more associated with Cutey Honey than anything else, at least in the West.
The speech can also be heard in the first Cyborg 009 movie, which must be a Tarao Bannai reference and not a Cutey Honey reference because that movie, from 1966, predates Cutey Honey.
