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.
YMMV: The Mr. Men Show
Animesque: This series feels a bit like an anime, especially with the typical Anime sound effects put to use. It also helps that the slight feel of it (ala twinkle eye and pupils disappearing when feared sometimes) is done also by Renegade Animation, the studio behind Hi Hi Puffy AmiYumi
Squick: Mr. Messy has some rather revolting habits, especially to a Neat Freak like Mr. Persnickety/Fussy.
They Wasted a Perfectly Good Character: Mr. Tall and Little Miss Curious. For most of Season 2, they were relegated to nothing more than cameos, and even their speaking appearances had little to no bearing on the plots of the sketches they appeared in. Mr. Tall would've had great plots concerning his height, and Little Miss Curious could start one off with a question. Alas, it was not to be.
Toy Ship: Despite the series aimed for young children, at one point, it seems, during Season 2, that the writers and animators were teasing of hints of Mr. Grumpy with Miss Chatterbox for some odd reason.
The Woobie: Mr Bump. He has Miss Whoops for a sister. I'd hate to be him. And in some cases, this trope can expand to Mr Quiet. Miss Calamity, until her disappearance in season 2, was also part of this trope.
However, since some people are amused by how Mr. Bump gets repeatedly harmed, you could describe him as The Chew Toy. Miss Calamity fitted this trope, too.
Mr. Happy is also considered one. There are some fans who feel sorry for him. While the Chew Toys/Butt Monkeys always express how they feel and get back on their feet, Mr. Happy has to hide his other emotions behind a smile and suffer in silence.
Mr. Nervous. He's practically scared of life itself!
Mr. Quiet - the poor dude is just looking for some peace and quiet but ends up being walked over by others or dragged into their mess.
