Here's a checklist and essentials for perfectly enjoying horror content on tropical nights.
Chilling content – horror designed to make you forget the summer heat – has been loved for a long time. In the past, TV's 'Summer Horror Special' dramas and theatrical horror films were dominant, but as of 2026, OTT platforms have taken over that role, offering horror content in various genres and formats.
Past: In the 1980s-90s, Korean broadcasters aired 'Summer Horror Special' dramas like Hometown Legends every summer, helping viewers beat the heat. Theatrical films such as Japan's Ring and America's The Blair Witch Project also dominated the summer box office.
Present (As of 2026): With the development of OTT, horror is no longer summer-exclusive content, but August remains a period for concentrated releases of new horror/thriller titles. Themes and genres are becoming even more diverse, including webtoon-based (Mousetrap, Netflix), real-story-based (Zodiac, Netflix), and K-creature features (Project: Island of Ruin, TVING). They also offer immersion comparable to cinemas with high-quality visual effects and sound. Furthermore, works that offer 'food for thought,' such as psychological thrillers and revenge dramas, are gaining popularity.
As of August 3, 2026, information on new horror/thriller films and dramas directly scheduled on Watcha has not been confirmed. However, a variety of new horror/thriller content can be enjoyed on other OTT platforms such as Netflix, TVING, Wavve, Coupang Play, and Disney+.
Yes, generally, there are differences. Netflix, based on its global content, showcases diverse genres of horror/thrillers, while TVING specializes in Korean-style creature features or webtoon-based thrillers, like Project: Island of Ruin. Wavve tends to offer broadcaster-based dramas and webtoon-based content, and Coupang Play provides a mix of popular international series and domestic films. Disney+ primarily releases novel-based thrillers or works with specific themes.
While it depends on personal preference, Netflix's drama Mousetrap, a webtoon adaptation starring actors Ryu Jun-yeol and Sol Kyung-gu, is garnering high expectations. Additionally, TVING's Project: Island of Ruin (Working Title), featuring Korea's first 'full-digital human' character, is expected to open new horizons for K-creature features. FX's The Shards on Disney+, based on a bestselling novel, promises a solid story.
