Avert your eyes, “Harry Potter” lovers. Out of the eight wildly successful “Harry Potter” films, the franchise’s star, Daniel Radcliffe, recently admited to hating one of the series' more successful installments, “Harry Potter and the Half-Blood Prince.”

“Doing 'Potter' was an incredible blessing because it gave me this opportunity to start a fantastic career,” Radcliffe, 25, recently told the Daily Mail of the decade he spent filming his title role in the blockbuster franchise. “But then the moments I’m not so proud of, mistakes other actors get to make in rehearsal rooms or at drama school, are on film for everyone to see.”

While Radcliffe has previously expressed his displeasure with his performances in the saga, he now claims the series’ sixth installment, released in 2009, causes him the most regret.

“It’s hard to watch a film like ‘Harry Potter and the Half-Blood Prince’ because I’m just not very good in it. I hate it,” he said. “My acting is very one-note, and I can see I got complacent and what I was trying to do just didn’t come across.”

Despite his distaste for the sixth film, a favorite among many Potterheads, Radcliffe admitted to treasuring one installment in the boy wizard tale. “My best film is the fifth one ['Order of the Phoenix'] because I can see a progression,” he said.

While Radcliffe may be overtly critical of his breakout childhood roles, the actor said the series’ creator, author J.K. Rowling, wasn’t nearly as negative when it came time to judge his performances.

“To my knowledge she was always very happy with the way I played,” he said. “But it’s my job to be critical … I’m seriously critical of myself. If I wasn’t, I would be worried. You don’t want to be the one people say: ‘Great, great, great’ to then turn around and think: ‘S--t, s--t, s--t.’”

Radcliffe’s new film, “As If,” is currently in theaters. Radcliffe helped debut the trailer for his newest project, Alexandre Ajas’ thriller “Horns,” at San Diego’s Comic-Con International last month. The film, based on the best-selling novel by Joe Hill, premieres Oct. 31.
