Lua Negra

While researching in the jungle with his girlfriend Marjorie (Johanna Marlowe Lebovitz) and a group of natives, Ted (Michael Pare) and the group are attacked by a beast and only the wounded Ted survives. When his sister Janet (Mariel Hemingway) learns that Ted is back home, she invites him to bring his trailer to her real property and spend some time with his nephew Brett (Mason Gamble) and her. Ted accepts the invitation when the police find several corpses attacked by an animal nearby his trailer. Ted is welcomed by Janet and Brett but their dog Thor estranges him. Soon Janet suspects and finds evidences that Ted is a werewolf and her family is in danger.

"Bad Moon" is a decent werewolf film, with reasonable story. In this film, Ted turns into a werewolf every night, and not only in the full moon. He comes closer to his beloved sister and nephew expecting that the love of his family heals or at least help him to control the beast within as his last chance. The dog Thor (Primo) steals the movie. My vote is six.

Title (Brazil): "Lua Negra" ("Black Moon")
