Desperate circumstances call for a miracle, which makes the pairing of the terminal-illness-romance subgenre with sacrifice-obsessed, faith-based storytelling an obvious match. As such, their fusion has now yielded “I Still Believe,” an overbearingly saccharine young love story with concert-movie undertones from writing-directing duo Andrew and Jon Erwin that’s based on Christian singer-songwriter Jeremy Camp’s career and first marriage.
“Riverdale” star KJ Apa renders Camp a wholesome college heartthrob and aspiring musician from Indiana with a go-getter attitude who, in 1999, meets Jean-Luc (Nathan Parsons, “Roswell, New Mexico”), his best friend and mentor, and Melissa (Britt Robertson, “Tomorrowland”), the girl he falls for at first sight.
