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.
Awesome Art: There is probably more than one person who preferred the human character designs. Aside from them managing to avert falling in to the Uncanny Valley and all of them actually looking good if not better, their faces, shape, and personality are honest-to-god faithful to their fish counterparts and beautifully diverse.
Cliché Storm: Possibly half the reason the show is So Okay, It's Average due to having plots that have been used before. These episodes usually take place in school. For example, you think we would've seen an episode about class pictures, passing a test, forgetting someone's anniversary before?
Critical Dissonance: The show has not been as well recieved by critics as someother animated Disney shows, but this show still scores about 3 million viewers on average each new episode. Not to mention the pilot, "Bea Stays In the Picture", scored a huge 4.8 million, which is about more than most SpongeBob SquarePants episodes.
Idiot Plot: "Milo's Magical Shake", and is it ever. Long story short, Milo gets his 1,000th milkshake for free along with 999 shakes he bought previously, names it Emily, and cherishes the moment rather than drinks her. Milo doesn't even consider drinking Emily even when she starts to melt, and his friends even hold an intervention!
Let's be fair though, Milo was the main character of that one. Besides, there are many, many other episodes who have idiot plots:
"Oscar is a Playa": Based on an asumption between Escargot and Oscar, and the truth doesn't come out until the episode is about to end.
They Wasted a Perfectly Good Plot: both fans and haters of the show agree that if the show was focused less on school, and more on the weirdness, it wouldn't be such a indecisive crowd. Needless to say, episodes like "Fish Out of Water" or "Peopleing" are better received than episodes like "Queen Bea" or "Fish Floaters".
"Pool Party Panic", a lot of fans preferred the human designs and found the characters much more interesting.
