Let’s stipulate two incontrovertible truths: First, as dazzling as Jennifer Hudson is, she is not the once-to-a-planet gift that was Aretha Franklin, whose songs are so deeply embedded in our collective unconscious that we cannot help but hear it in our head and accept no substitutes. Long past her prime but every inch a diva of raise-the-rafters soul singing, the clip over the credits of Franklin singing “Natural Woman” at the Kennedy Center Honors tribute to songwriter Carole King (Franklin won her own Honor 21 years before), is breathtakingly thrilling. We see her bringing King and President Obama to tears, and I expect most will see that through their own.

Second, there are a lot of movies, many fact-based, with the theme: good woman, great songs, bad, bad men. For example: “Love Me or Leave Me,” “Piaf,” “Judy,” “Phantom of the Opera,” “The US vs. Billie Holiday”/”Lady Sings the Blues,” “What’s Love Got to Do With It,” “A Song is Born,” “Coal Miner’s Daughter.” It is a challenge to make that story new, especially after the take-down of the inevitable cliches of singer biopics that is the excellent “Walk Hard: The Dewey Cox Story.”

Despite these obstacles and a 2 1/2 hour running time, the Aretha Franklin story simply titled “Respect” is absorbing and entertaining. Hudson may not sing Aretha’s songs as well as she did, but the Oscar she got for her very first movie role in “Dreamgirls” was an accurate assessment of her acting skills and screen charisma. Director Liesel Tommy and writers Tracey Scott Wilson and Callie Khouri have skillfully shaped a complex, even epic story to skip over many relationships and crises to focus on two key themes, the songs and their depiction of Franklin’s evolving voice, first in music, then in activism, then on her own behalf, and finally and most fulfillingly, to connect to God.

We first see her as a young girl, living with her father (Forest Whitaker), a prominent preacher, her grandmother (Kimberly Scott), and her sisters and brother. She is used to being awakened to sing at her father’s parties, which include prominent activists and performers. Her parents are divorced and she wishes she could spend more time with her adored mother (Audra McDonald), but overall she is happy and secure. In a wonderful scene, her mother gets her to express her feelings by singing them.

And then two cataclysmic events literally strike her silent. She is molested and gives birth to a son at age 12 and another one two years later. And her mother died.

Music is what literally gives her voice back to her. She sings, and that leads her first to tour churches with her father and then to make her first record deal, with a label that wants her to be a jazz singer. She marries Ted White (Marlon Wayans), who is threatened by anyone she wants to work with and hits her. She works with Martin Luther King. And then she starts to get the hits she has wanted.

Hudson is never less than dazzling and the film manages to give a sense of the scope of the story without getting caught up in details like the husband it just skips over. The film is ultimately, yes, respectful, just as Miss Franklin hoped.

Parents should know that this film includes domestic abuse and child molestation, sexual references and non-explicit situations, substance abuse, very strong and racist language, and some violence.

Family discussion: Who treated Aretha Franklin well? Why were hits so important to her? What made her able to start standing up for herself?

If you like this, try: “Amazing Grace,” the documentary we see being filmed at the end of this movie, the documentary “Muscle Shoals,” and of course listen to Ms. Franklin’s music
