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.
Crack Pairing: Joey-Heroman fanart has become rather popular, especially after episodenine, and helped not at all by how confusingJoey can be and that his mom and dad look just like him and Heroman, respectively.
Crazy Awesome: Half the stuff Denton comes up with simply could not have been conceived by a sane, rational mind. Doesn't limit its effectiveness, though.
Then there's Holly. Investigating serial kidnapping in Central City? Forcing Joey and Psy to dress like stereotypical detectives? In attempt to lurk into hospital forcing them all to Recursive Crossdressing? Drinking so strong coffee with so much sugar that her head would explode?
Ensemble Darkhorse: Ms. Collins, the hot red haired homeroom teacher, was featured in way more fanart than the few seconds of showtime in the first eleven episodes would indicate. She has become part of the comedic plot in episode 12, and was involved in Episodes 18 and 19, mostly concerning Fanservice.
Growing the Beard: A lot of people who watched the show were "Meh" during the first arc, but by the time the second arc finished, people were saying "HOLY SHIT!".
Hilarious in Hindsight: Will, the resident Expy of Flash Thompson, ended up becoming an Expy of Venom. in recent Spider-Man comics, Flash Thompson is now Venom.
Tear Jerker: Episode 22, everything about the death of Joey's dad.
Putting in spoiler tags for anyone who wants to find out themselves, but he died ON CHRISTMAS EVE! WHY, STAN, WHY?!
Ugly Cute: The MR-1. Just look at that mouth and try not to smile.
Viewer Gender Confusion: Despite material clearly stating that Joey is male, Joey's appearance in both the anime and manga, and his voice, and his Genki Girl heroine attitude, and pretty much everything about him, have convinced many a viewer that he's a reverse trap.
Villain Decay: Inverted, while both antagonists started out beaten fairly easily, both come back even stronger, Minami actually used the combat data gathered from his battle with Heroman, and used it to his advantage, Kogorr is an Eldritch Abomination that has eaten many planets before, and keeps the Dangerously Genre Savvy behavior that made him such a huge threat in the first place.
The Woobie: Lina's progress in her relationship with Joey tends to get dampened by her separation from her brother Will and by constantly getting Locked Out of the Loop by Joey and the others. The latter doesn't sit too well with Lina in Episode 23 when she discovers Joey kept it a secret that he previously encountered Will.
