H2O, also known as H2O: Just Add Water, is an Australian television series geared towards children and teens that aired on Nickelodeon from 2006 to 2010. Combining elements of fantasy, adventure, and teen drama, the series presents an imaginative exploration of friendship, secrets, and the supernatural. At its most fundamental, the series centers around three teenage girls - Cleo, Emma and Rikki. They live in the coastal town of Gold Coast and despite having different personalities, the girls are inseparable friends. The premise of the show centers on the major transformation the girls undergo after an excursion to Mako Island, a fictional place in the show. A visit to an ancient underwater cave exposed them to the light of a full moon reflecting off the water, which awakens a dormant lunar spell that changes their lives forever. The girls develop the ability to transform into mermaids upon contact with water, a power that comes with its fair share of trials and tribulations. Emma, played by Claire Holt, is the most responsible and organized one of the trio. She is a competitive swimmer who initially struggles with her newfound mermaid identity as it interferes with her disciplined lifestyle. Cleo, portrayed by Phoebe Tonkin, is the heart of the group. Despite her initial fear of water, Cleo adjusts to her mermaid powers, even learning to control water. Rikki, played by Cariba Heine, is the rebellious and independent one in the group. Her temperament is akin to her power to boil water, but she also shows deep loyalty towards her friends. Apart from the girls' struggle with their new identity, the show also emphasizes their bond of friendship that helps them navigate daily challenges of adolescence -- dealing with family, school, relationships, and of course, keeping their mermaid secret hidden from the world. H2O is not just about the excitement of mermaid magic. It also does a commendable job of grounding the characters in reality and showcasing genuine issues teenagers grapple with every day. It is a series about growing up, friendship and self-discovery; a tale of dealing with change - both ordinary and extraordinary. Each episode usually features a standalone adventure, with an overarching plot that gets explored throughout the series. Despite the fantasy element, the show also pays tribute to its beautiful Australian setting. It beautifully captures the breathtaking landscapes of Gold Coast’s coastal region, the warm sandy beaches, the crystal-clear water and the city's wider environment, which adds an extra charm to the series. Adding to the list of unique features that differentiate H2O from other shows in its genre, is its attention to the creatures of Mediterranean folklore. The series doesn't just focus on the concept of mermaids as fantasy beings, but incorporates their folklore into its narrative and uses it as an integral part of the storyline. Moreover, the series also places strong emphasis on environmental conservation. The girls, in several episodes, are shown standing up against those who seek to harm their marine world, indirectly encouraging awareness about our natural environment. The cast delivers a fantastic performance, grounding their characters in a reality that is relatable to the viewers. The lively music and catchy theme song add more life to the series, making it all the more engaging. In conclusion, H2O is a unique blend of teenage drama and fantasy, capturing the attention of viewers through its magical storyline, relatable characters, and breathtaking settings. It’s an endearing coming-of-age series that both entertains and enlightens, reminding audiences of the complexities of adolescent life, the strength of friendship, and the magic of believing in the extraordinary. With its universal themes and its unusual premise, it's not surprising that the show continues to engross audiences long after its original run.

H2O is a series categorized as a canceled. Spanning 3 seasons with a total of 91 episodes, the show debuted on 2006. The series has earned a moderate reviews from both critics and viewers. The IMDb score stands at 7.3.
