YMMV / Gangs of London

• Adaptation Displacement: A few know that this series is based on an obscure poorly reviewed PSP game of the same name.
• Americans Hate Tingle: A number of viewers - particularly Rocci Williams - expressed annoyance at the stereotypical depiction of Gypsies and Travellers. Some feel it borders on Modern Minstrelsy.
  "How can we let viewers know that they are Gypsies? I know, dress them like they've walked into a 1980's Oxfam."
• Complete Monster:
  • Season 1:
    • Unche "Mosi" Mossanya is an understated, but brutal Nigerian crime boss, whom even other mob bosses fear due to his viciousness. Introduced drowning a pleading victim in concrete to become a support pillar in his new building, with the heavy implication this is a common tactic of his, Mosi strikes a deal to construct a luxury skyscraper in London with Luan. Following the money being stolen, Mosi takes it as personal affront and arriving in London, has his men massacre the investment bank that handled the deal with machetes despite them being unknowing civilians, chopping off their hands before hacking eleven people to death. Threatening to murder Luan's entire family, after capturing him Mosi has Jin Li, who sold Luan out, carved to death, despite promising Li he could go. Putting off killing Luan solely to force him to watch as Mosi kills his wife, Mosi's only regret is that he can't yet do the same to Luan's children.
    • Episode 3: Cole is a smug, creepy sadist who works as an infamous hitman, his actions disgusting even hardened gangsters. Hired by Sean Wallace as part of his plan to deal with Lale, Cole attacks her base, murdering several workers and kidnapping Lale's sister and her two young children. While Sean only intends to intimidate Lale, Cole has no intention of letting the family go. Murdering Sean's doorman for attempting to assist him whilst he was wounded, Cole gleefully beats Eliot Finch within an inch of his life, only holding off on killing him to force him to watch as Cole slowly murders the children with a fire axe.
  • Season 2: Koba is a swaggering, sadistic, yet pragmatic Georgian crime boss and international Arms Dealer, who unlike most gangsters holds no standards and views love as a weakness. Brought in by the Investors as their enforcer in London, Koba pushes the gangs to the breaking point whilst taking most of their profits, punishing any disobedience by brutally torturing their loved ones. Following the Algerians buying unsanctioned guns, Koba forces Faz to swallow three bullets before making him murder his own cousin. Discovering Luan's dealings with Miriam Wallace, Koba kidnaps his beloved Mirlinda, forcing Luan to torture Miriam's location out of Darragh and then sends a helicopter to wipe out her compound. Despite promising to return Mirlinda, Koba instead has her Buried Alive to force Luan to hand over his entire operation. Capturing Ed Dumani, Koba brutally tortures him for hours, intending to keep him alive as a source of knowledge, then slowly kill him and his family when that runs out. Hungry for more power, Koba accepts Sean Wallace's deal to betrayal the Investors, leading to them being rapidly murdered, and take London for themselves. To secure his position, as a "sweetener" for their deal, Koba kidnaps Lale for Asif to torture to death.
• One-Scene Wonder: Cole only has a few scenes in Episode 3, but is quickly established as an sinister, savage, and utterly ruthless assassin. So far he's the only character to actually beat Elliot... and then Ed comes along and guns him down.
