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.
Ensemble Darkhorse: Sakura is way up there along with Jasmine as one of the candidates of 'Hottest Sentai girl ever'. Most people would also agree about her being a fan favorite due to how different she is for Pink Rangers.
Family-Unfriendly Aesop: For Eiji: He's mixed-race (Human/Ashu), but that's okay, as long as he actively fights his racially undesirable side! This Aesop is especially strange since it was shown that his mother was kind-hearted which means Always Chaotic Evil should be averted, but alas...
Fridge Brilliance: Natsuki/Bouken Yellow being a Lemurian Princess would look normal, unless you realize that back then in Dai Sentai Goggle Five, Lemuria is the civilization symbolized by Goggle Yellow.
Hilarious in Hindsight: Unless their numbers are being multiplied by special effects, you only seem to see a maximum of three Jaryuu on the screen at once, much like Land of the Lost, where you only saw three Sleestacks on camera at once because that's how many costumes they could afford.
Ho Yay: The sequence where Natsumi imagined she was Cinderella and Sakura was Prince Charming.
Irony: Despite being one of the most loved Sentai series, it's American counterpart Power Rangers Operation Overdrive is considered by some people to be the worst season in the entire franchise.
Even more ironic is the contrast between fans' opinions of the rangers themselves; Sakura (BoukenPink) is a fan favorite (see Ensemble Darkhorse above), but Rose (Pink Overdrive Ranger) is considered to be one of the worst female rangers of all time. And Natsuki (BoukenYellow) is at times seen as The Scrappy, but Ronny (Yellow Overdrive Ranger) is the American fan favorite. And that's only the beginning. It's almost like Disney butchered Operation Overdrive solely to contradict everything in its source material.
Magnificent Bastard: The Questers. When you can not only manipulate the three main evil factions to provide the materials for the ultimate lifeform, but also unleash a long-lost cousin to keep the Boukengers further occupied, you're pretty magnificent in your bastardry.
Memetic Mutation: Let's just say Masumi is better remembered by his crooked teeth than by his actions.
