The Secret Garden is based on Frances Hodgson Burnett's classic children's novel.
It has moments of mild peril but essentially deals with grief in a positive manner. It's very much a coming-of-age tale, as young orphan Mary Lennox (Dixie Egerickx) must adapt to a new culture and learn vital life skills, including compassion, following the death of her parents. She achieves this through a combination of friendship, curiosity, and imagination. Her new optimism also inspires her widowed uncle, Lord Archibald Craven (Colin Firth) -- who, it's suggested, drinks to relieve the pain of losing his wife. Mary suffers from nightmares and hears gunfire in her sleep, suggesting she witnessed violence while growing up in colonial India. A dog is in distress after being caught in an animal trap, resulting in a bleeding leg and a limp. There's also a major house fire, and while nobody is injured, it's tense and nerve-wracking as the characters struggle to escape. Overall, this adaptation has positive messages about the power of curiosity and imagination and could help inspire a love of nature.
