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.
Fridge Brilliance: Why are the Megaranger suits the same safe color and a slight tweak of vizor shape? It's cause this season heavily involves video games, and in the mid-90s when this came out, Palette Swaps were common.
Ho Yay: In episode 6, Miku tells a boy that wants to date her that she likes another person. When the other Megarangers asked who that is, Miku grabs Chisato's hand and goes to take her for tea. It's a minor example as, later on the series, it's revealed that she likes Shun, as well as Chisato being shocked by Miku's choice and actions.
The Scrappy: That girl from #39, who finds out Megared's identity and blackmails him to do everything for her. Annoying brat.
The episode where Kenta adopts a baby Nejireija, who is absorbed into the Monster of the Week, forcing Kenta to kill them both.
Episodes 49 to the end is a series of Tear Jerker for the Megarangers. Once their identity got exposed and their battle accidentally wounded one of their friends, the rest of their friends AND the whole school turned against them and drove them out of school, forcing them to take refugee in an abandoned house. Miku was nearly crying all the time and Kenta was even driven to despair so much he thought of stopping being a Megaranger and tossed aside his Digitizer. Though from that point on, it's basically Earn Your Happy Ending from their Darkest Hour. And they do, with them being accepted back to school and even graduate.
