At Sunday night's Oscars, "Amy," the documentary about late singer Amy Winehouse, took home the award for Best Documentary. Even though director and producer Asif Kapadia dedicated the award to Amy, her father, Mitch Winehouse, was still very open about his negative thoughts on the film's portrayal of his daughter.

When the documentary first aired in Cannes last summer, viewers and critics thought it perfectly captured the singer's beautiful and artistic yet tragic life, but Mitch and the entire family, were not pleased, according to The Hollywood Reporter. "I felt sick when I watched it for the first time. Amy would be furious. This is not what she would have wanted," he said at the time.

He went on to explain how the film portrayed him as a father "in the worst possible light," especially regarding the famous lyric "if my daddy thinks I'm fine" in her hit song "Rehab." While Amy was binge drinking at the time, he claims she was not drinking every day, which is why he believes she did not need to seek treatment for her addiction in 2005. "What I said was she didn't need to go to rehab at the time," he explained. "They've edited me out saying 'at the time.'"

When "Amy" won the Academy Award on Sunday, Kapadia and producer James Gay-Rees accepted the award and paid tribute to Amy, who passed in 2011 at the age of 27 from alcohol poisoning, but this still wasn't enough for Mitch. In his acceptance speech, Kapadia described Amy as "funny, intelligent, witty - someone special, someone who needed looking after." He went on to say that "they just wanted to make a film to show the world who she really was."

"This is for Amy's fans," Gay-Rees added. "Who loved her through thick and thin."

Shortly after, Mitch took to Twitter to slam Kapadia once again. "Always proud of my baby. Amy will not get an Oscar though. Just Asif Kapadia. This is what this is all about...Asif. He's fooled everybody," he wrote, adding, "I am not changing my stance just because film won Oscar. It's a negative, spiteful and misleading portrayal of Amy. We will fix this."

Last summer, Mitch even said that he would create a new movie in response to Kapadia's film to better represent his daughter, according to E! News. "We're going to invite everyone that's spoken on the other film and we're not going to edit it, like they've edited me," he said while on the British talk show "Loose Women." "And we're going to tell the truth about Amy's life because this is not."
