Two good songs (Light of Day and This Means War) are not enough to save this rock and roll movie. Joan Jett's acting consists of reading her lines with a face fixed in a snarling sneer. or is it a sneering snarl? No matter. Michael Fox will try to fix it all with his unwavering look of quiet concern and a few bobs of the head.There is, I'm sure, a good movie waiting to be made about bar bands in gritty rock and roll clubs. Unlike Light of Day, it will have characters we can care about, acting that we can believe in and some development that makes a difference in the characters' lives.A man ten rows behind me in the theatre where I saw Light of Day fell asleep and snored through the last half of the movie. No one bothered to wake him. Just jealous, I guess.
