If you are in love with the 1970s and Johnny Depp, perhaps you will enjoy this. Andrew O’Hehir says he knew he would love the film when he spotted a banana-seat Schwinn bicycle leaning against the front porch of Collinwood in an early scene. All right. But then comes a “happening” featuring Alice Cooper as himself (!), with a disco ball and cage dancers. At Collinwood. Is this really anyone’s idea of a good time?
