Broken Base: This is one of the more divisive and polarizing series' in not just the UCverse, but in the entire Gundam franchise. Some people like it just fine, but others really hate it, deeming it one of the worst Gundam shows ever.
Complete Monster: Fonse Kagatie, the elderlyPrime Minister of the Zanscare Empire, cynically exploited the messianicpsychic Maria Armonia's harmless pacifist cult to create a brutal military dictatorship, with Maria as his powerless figurehead. As the de facto ruler of Zanscare, he was responsible for green-lighting all of its atrocities, which included the mass execution of dissidents by guillotine, burning entire towns to flush out the League Militaire, and genocide by giant motorbike). His worst act was creating and deploying the Angel Halo. The Final Solution to Zanscare's war with the Earth Federation, the Halo was a psychic Doomsday Device designed to wipe out all intelligent life on Earth via Mind Rape, allowing Kagatie's empire to move in and take the planet unopposed. The power source was Maria (later replaced by her eleven-year-old daughter) and thousands of her followers, whom he tricked into believing that they were broadcasting messages of peace and goodwill rather than orchestrating a total planetary genocide. This also meant that they served as human shields for the Halo, ensuring that every bit of damage it took was measured in innocent lives.
Critical Backlash: Katejina is a character example. The hatred that the fandom has for her is so extreme that, once you've been exposed to it, you may well find yourself noticing her (very few) good points, since you are taking her evil for granted.
Darkness-Induced Audience Apathy: Victory Gundam is one Tomino's most violent series next to Space Runaway Ideon; however, unlike Ideon which became famous thanks to its over the top and violent finale, Victory tends to be criticized for its focus on torture, incredibly mean-spirited characters and even misogyny, which as a whole tend to make the series a chore to watch for some people.
Not just as earrings, but pretty much everywhere on her.
These wigs. These old fashioned, really stupid looking wigs. Wigs have been a fashion statement for centuries, and are still used today in British courtrooms, but they generally look considerably more stylish than the ridiculous, spidery affairs the Zanscare elite are afflicted with.
Note that the bells are explained as being linked with crazy!Fuala's obsession with the guillotine (they were the same kind of bells worn by the ones to be executed).
Katejina deciding to sicc some bikini-clad soldiers with Anti-MS weaponry on Uso while he is in his Gundam, although given that the chains of command had basically broken by that point and Katejina was so far off the deep end the fact it was a terrible plan that made no sense was entirely the point. It also depicts how horribly brainwashed the few remaining forces of the Zanscare are for even being willing to participate in such an attack.
Katejina's plan actually made some sense if you look at it from a sufficiently twisted perspective. As far as mid-series Uso had severe problems using deadly force against the opponents whose faces he could see, and was easily flustered by anything remotely erotic. The sight of the bikini squad MIGHT have left Uso, as he was around episode 20, incapable of fighting back. The terribleness of the plan was in the assuming that Uso was not hardened by his war experiences since then.
There's a few others as well: Chronicle's death being ruined by a THUDright before the Eye Catch is a good exemple.
Arbeo's isn't better: look at this face ! It's easily one of the few deaths of the franchise that can double as a funny.
The Woobie: All of the Shrike Team because of how none are left alive at the end of the series. Hell, the first member to die, Helen, was killed off one episode after they debuted! Even worse is how the last member, Connie, proclaimed she's protect Uso as the last surviving member of the team only to be unceremoniously killed by Katejina moments later.
