According to a recent thread on Reddit, some fans think “Harry Potter and the Prisoner of Azkaban” still had poor acting, even with its star-studded cast. For u/Dillidolli, it was Daniel Radcliffe in particular. They simply said, “He was their friend!” This line appears in the scene of “Prisoner of Azkaban” where Harry discovers how he is connected to Sirius Black (Gary Oldman): The escapee from Azkaban was his father’s best friend at Hogwarts and would have betrayed him, him and his mother, to Voldemort, dragging them from the dead.
Naturally, Harry is incredibly upset, and when Ron and Hermione find him, Harry explains, “He was their friend, and he betrayed them”, before ending with “He was their friend!” Other fans, like u/JBTheGiant1, u/always_ella_15, and u/ThePrincessSparkles, agree that Radcliffe’s depiction of upset Harry isn’t so great.
While this is only opinion and certainly debatable among fans, Radcliffe himself noted that he often looked back on his acting in the early “Harry Potter” films with embarrassment. However, he and many other cast members have reflected positively on their time with “Harry Potter” in the HBO Max special “Harry Potter 20th Anniversary: Return to Hogwarts” – bad acting or not.
