Where Were You When the Lights Went Out? was never, ever a good film, but the passage of time has made it even less entertaining. Most modern viewers are likely to have a problem with the underlying morality of the piece, which essentially says that a man should be forgiven for cheating on his wife, but that he has every right to be outraged and feel the offended party if his wife turns around and cheats on him. As might be expected, there's a puerile smarminess that permeates Lights, a kind of arrested adolescent view of sex that's unpalatable. If Lights had a screenplay that was filled with witty lines and bright dialogue, this might matter less; unfortunately, the closest Lights comes to anything approaching inspiration in the writing is when the gap-toothed Robert Morse stops in mid-conversation with the equally-gap-toothed Terry-Thomas to ask who does his dental work. Terry-Thomas, along with Patrick O'Neal, is hard to take here, but Lights does have Doris Day and Robert Morse on hand to enliven things. They can't make the film good, but they do give it their best shot, which is saying something. There are also such stalwart character actors as Jim Backus, Steve Allen, and Pat Paulsen -- plus an enjoyable "groovy" title song -- to help things along.
