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.
Big Lipped Alligator Moment: The beginning of the tournament's second day is celebrated with a musical performance by the Star Wars Cantina Band. Pan and Tapion enjoy the musical interlude, Bra, Frieza's Family and Babidi do not. Zen Buu thought it was so bad that he demanded that they give their instruments to him so he could play.
Super Buu ( given he absorbed lots of people in his universe), and the 'Super Saiyans' have shown shades of it, and the Frost Demons (King Cold, Cooler, and Frieza).
Creator's Pet: Broly and Vegetto. Despite Universe 18 being the canon universe that we know and love, an irritatingly large focus is put on the fight between Vegetto and Broly, with the characters from Universe 18 going on and on about how powerful the two are. They exaggerate Broly's power, moving him from "extremely powerful" to "invincible" while in his Legendary Super Saiyan state.
Bra too, given that she's absurdly overpowered (to the point where Goku and Vegeta, the main characters of the original damn manga, worry that she may be stronger than them!), an absolute Jerkass to most other characters, gets praised even when she directly goes against orders and also receives an irritating amount spotlight alongside Vegetto.
Fan Dumb: The fans who were outraged by the result of Pan vs. Bardock fight. Despite the fact the difference of power should be really obvious.
That and the people cheering when Bojack killed a little girl because they don't like her GT character, even though GT doesn't exist in this continuity.
Some other moments of Fan Dumb include vocal arguments of Vegetto's marriage and living arrangements with Chi Chi and Bulma, how Bra at SSJ2 can injure her already half dead father with a full power blast and quite recently how Cell was looking the wrong direction.
U13 Vegeta's fight against Syd, besides fueling Ho Yay Shipping as hell, started a discussion in the French version about the treatment of homosexuality in Japan and, eventually, a discussion about Yamcha's supposed homosexuality.
The fans who said that the Universe 8's plan to steal Dragon Balls was already over in page 524. Even though it was the very first page of the chapter, and you would expect Frieza to have a better plan than just send a mook to try to sneak past a mind-reading man roughly a million times your strength in broad daylight and in an obvious manner without cover or distraction.
Filler: Despite giving the backstories of many universes, the Special Chapters in general get a lot of flack for NOT being about the tournament. To add fuel to the fire, are often the varied art styles different from the tournament chapters.
I Knew It: Back when the 18 vs. Yamcha fight started, a few fans predicted that Yamcha was actually a cyborg. A few pages later, this was confirmed.
U16 Bra certainly counts, since the canon incarnation of the character is basically just a space filler.
Uub may also qualify. While it's true that he had a supporting role in GT, he quickly (and I mean quickly) became unimportant and something of a small fry. In DB:M he at least gets to show off a bit.
The Super Saiyan 3 form. Its role in the original series was relatively minor, gets glossed over fairly quickly and is just impractical to use. On top of everything else it looks pretty dumb. DB:M manages to portray it as a churning maelstrom of barely-contained power, giving the form much more 'oomph'.
To a minor extent, the special themselves. While chapter 14, 16 and especially 18 have been panned by pretty much everyone (as you can see below), the next special, despite being even longer than all of them, as it lasted for two chapters, was received well enough for most readers to be again interested in them. The Universe 7 special was well received as well.
