Amazon Prime’s Harlan Coben's Shelter is the latest addition to the slew of supernatural teen-led mysteries that have come out in recent years. Like Netflix’s Lockwood & Co., Paramount’s School Spirits, and even Showtime’s Yellowjackets, Shelter is genuinely intriguing and surprisingly mature, making it watchable regardless of how old you are. The show’s TV-14 rating lets the teens in the series act their age (that is, both crude and childlike), which adds to the show's authentic feel. It verges on being self-serious at times, which is funny when you hear them say things like “Octo Face got her” with a straight face, but those slips are forgivable. It doesn’t detract from the show’s compelling mystery and enjoyable performances.
