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.
Crowning Music of Awesome: Shademan's theme from Axess. So much so that the Dub version used the same one as the Original version oddly enough.
Could be said of the series in general, once it hit its stride during Axess. The score during the original seasons were acceptable, with only a few notable themes. Sadly, more than likely because everyone had given up on it by then, the scores from Axess onward were never released - which is a shame, because that leaves fans attempting to sample songs for themselves.
Seasonal Rot: Every season can get accused of this. Axess gets accused of it for the shift in tone, Stream gets it for exaggerating it further, Beast Plus for basically becoming a stream of Filler. Every season has it's fans, though.
Villain Decay: The WWW starts out as a fearsome organization bent on domination of both the real world and cyberspace. By the middle of season 1, they're running a curry shop together, where they have no qualms about cheerfully serving the heroes. They claim to be just as devoted to evil, though.
What an Idiot: In episodes 18-19, Maylu putting on the chip without knowing of the effects on Roll. Additionally, Roll herself didn't try to get suspicious on the chip she has at the time.
Also, MegaMan being fooled into thinking that Roll is back to herself despite her form is not yet normal counts as this.
Jerkass Woobie: In Axess, Chaud himself suffered majorly when he was forced to use a Dark Chip on Protoman.EXE to save not only Lan and Anetta but Megaman as well. While Chaud was rather cold to Lan during their confrontation episodes later, you can't help but to feel bad for the guy.
