Obsession, the horror film everyone is still talking about, centers on a deceptively simple warning: Be careful what you wish for. A hopeless romantic, desperate for his crush’s love and attention, wanders into a magic shop, where a red-and-yellow box catches his eye amid a display of otherwise banal knickknacks. Inside is the One Wish Willow, a magic stick that promises to grant its owner a single wish within 24 hours. With its bright colors and old-timey comic-book design, it looks as harmless as a prize pulled from a Cracker Jack box. Instead of giving this cute novelty gift to his beloved, he uses it himself, wishing she would love him more than anything else in the world. From there, a universe of terror unfolds.
