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.
Ass Pull: The writers were very forthright that the last four episodes of the season (drawing many seemingly insignificant plot threads together) were rewritten in response to fan whining. Though the precise mechanics of Lothor's Evil Plan do fall close to a Gambit Roulette of the highest order, the little details don't work and it's clearly a retcon. (Most of) The fans don't seem to care, making this a fine example of Author's Saving Throw.
Crossover Ship: While not a romantic ship (mostly), Dustin and Chip from Mystic Force are commonly written together as good friends due to their nerdy nature (as well as being the only two male Yellows in the franchise thanks to Saban's decisions from MMPR through Wild Force.
Actually, there's also Tideus of the Mighty Morphin' Alien Rangers, but most people don't even know he exists.
Crowning Moment of Awesome: Cam and Kiya's fight in "The Samurai's Journey, Part 2." Made even more impressive when viewers learn that Kiya is Lothor's younger self.
Vexacus viciously taking down Zurgane in "General Deception, Part 2."
Informed Wrongness: Dustin in "Tongue and Cheek". He does develop some Acquired Situational Narcissism, but he gets chewed out well-before then (which could explain why he would let the fame go to his head). And the one character really letting him have it is Shane, who later admits he was being jealous.
