To Save a Life is an incredible movie about pushing boundaries, stretching comfort zones, and realizing what's important in life. While some of the themes are more mature than you generally find in a Christian film, the movie is "real" and speaks to teens on their level.
Be forewarned, TSL is meant to get your attention and impress a powerful message to viewers. It's not the "feel good" movie of the year, but it might just be the most important movie of the year!
