Happy death day is very good movie. It contains too much mystery after first scene. A girl who name is tree. And complete film runs around her. On her birthday he kill by someone and after her murder, her day restart. She try to explain the all incidents to many people but they can't understand clearly but one boy understand.she try to slove mystery by her way. Finally her roommate was her murderor. Film give us some message. Its a great movie.
