On Tuesday night, former child star Alisan Porter won Season 10 of The Voice, marking the first time a female coach’s contestant claimed the top prize. The crowd went crazy when the California folk singer, who was on Christina Aguilera’s team, was crowned the winner. It led to an adorable moment as Porter, 34, cradled her young daughter on stage, singing her victory song with tears in her eyes:

While Porter deserves the trophy, her victory highlights one of the best aspects of NBC’s hit singing competition show — as well as one of the worst.

Let’s start with the best: Sometimes, the show really does prove inspirational. Porter, who briefly gained fame as the star of the John Hughes movie Curly Sue at age 10, had a truly moving story.

As she said in her first audition, Porter is a former alcoholic who got sober nearly eight years ago. She has said in interviews that she used alcohol as a coping mechanism when she quit acting. During her most personal moment of the season, she sang Patty Griffin’s Let Him Fly, which she said represented a dark time in her life when an ex-boyfriend died. In addition, Porter said, “I was at the end of my ropes with my addiction.”

The coaches praised her courage for sharing her struggles. “I think that the mark of someone who is an artist is someone who uses everything in their life, good and bad, to kind of speak through the music,” Adam Levine said. Aguilera echoed that sentiment, and later called Porter, now married with two kids, “an inspiration for everybody and anybody that literally has a dream and just wants a second chance.”

As a result, watching Porter’s rise this season was thrilling, especially as she revealed singing was her true passion; not acting, which she pursued for the first part of her life. Though that leads into what some consider one of the worst elements of The Voice — that people with lots of show business experience have an unfair advantage.

Cinderella story singing competitions like American Idol may be partly to blame for this, as that show (with strict policies against contestants who had previous ties in the music business) reminded everyone how glorious it could be to watch an everyday person suddenly become a star. The Voice has never shied away from its recruitment of great singers and, because of that, the show features many who are taking a second crack at stardom.

This has led some to question Voice contestants like Meghan Linsey, formerly in a modestly successful country duo; Cassadee Pope, who toured with Fall Out Boy; Jermaine Paul, who won a Grammy for an Alicia Keys collaboration; Tessanne Chin, a singing star in Jamaica; or Craig Wayne Boyd, a longtime Nashville songwriter.

Like Porter, all of those contestants did well in the competition, either winning or coming in second place. While Porter never gained much attention for her music career, she’s had showbiz experience, and has released two albums. In addition to her early Hollywood years in movies and TV, she starred in plays and became pals with American Idol star Adam Lambert, as the two were both in The Ten Commandments: The Musical.

Knowing that someone has industry connections takes some of the fun out of singing competitions like The Voice, which are always best when they discover complete unknowns. (This season’s third place finisher, Hannah Huston, is a preschool teacher from Nebraska.)
