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.
Anticlimax Boss: Catastrophe is built as a very serious threat and described as "the most powerful supervillain ever to terrorise the galaxy." And yet upon his first true appearance, he does nothing more than knock around a few Red Shirts, take several laser blasts, overpowers Horace and beats him up. Before having his powers taken again by Oliver and Kaz, and being defeated by Alan.
Evil Is Cool: Special mention goes to Skylar Storm in Season 2.
Becomes Ascended Fridge Horror in Season two, when the second episode "Lair, Lair" is kicked off with a hero actually brought in near death, cause the Annihilator stole there powers and there nemesis attacked them while they were vulnerable. And at the end after retrieving the powers only six heroes are shown there to receive there's back (though there could be more off screen) suggesting the rest of them have actually been killed, cause of Annihilator.
However, Bradley's character is still very much careless and a magnet for mischief, like Gabe.
Debby Ryan, who mostly plays a somewhat introverted, nerdy, socially awkward and even Butt Monkey-ish character in her most well-known Disney Channel roles, gets to play a famous and far overconfident rock star who also happens to be a superheroine no less.
They Wasted a Perfectly Good Plot: The whole series. The idea of two normal kids who work at a secret hospital for superheroes? That sounds awesome! The problem is they focus way too much on trying to make it funny. Even the Big Bad comes off as an idiot rather than an actual threat.
Debatable, while the series has a lot of humour, there is also a strong blend with seriousness. It happy explores the characters dynamics, relationships etc. while opening up many interesting plots. And it does have darker elements while the majority of the villains fall into Laughably Evil, they are still present as being very dangerous (for example a lot of stories actually involve heroes in the hospital needing immediate treatment following there most recent battle going wrong), many come very close to outright killing the protagonists. All the action scenes are always played straight. Likewise season two is noticeably darker, with new Big Bad the Annihilator being considerably more competent and dangerous than the previous one.
