Joffrey Baratheon
Joffrey Baratheon, a character who invokes disgust and hatred in viewers and readers alike, is a testament to the acting prowess of Jack Gleeson. It's crucial to remember that Gleeson's portrayal should not be confused with his real-life persona, and he shouldn't face any backlash due to the character he portrayed. His ability to make Joffrey detestable indicates an exceptional performance.
Visually, the casting of Joffrey in the show is equally effective. Interestingly, unlike other characters aged up by two years, Joffrey was up by four years in the series, offering a unique departure from his book counterpart.
