Angel Movies: Release Order
The Angel series is a gritty 1980s exploitation thriller franchise that follows Molly, a teenager living a double life as "Angel" on the streets of Los Angeles. The series explores themes of survival, crime, and urban decay through its protagonist's encounters with violence and corruption.
The first three films form a complete trilogy, with each entry recasting the lead role while maintaining story continuity. Angel III: The Final Chapter was intended to conclude the series, but a fourth film was produced six years later with only loose connections to the original trilogy and is generally considered non-canonical by fans. Also, it's terrible.
