And yet, perversely perhaps, I found this an interesting movie. I didn't give a bean how it turned out, and I found a lot of it preposterous, but I enjoyed that quality. Why do we look at movies? To learn lessons and see life reflected back at us? Sometimes. But sometimes we simply sit there in the dark, stupefied by the spectacle. "Mermaids" is not exactly good, but it is not boring. Winona Ryder, in another of her alienated outsider roles, generates real charisma. And what the movie is saying about Cher is as elusive as it is intriguing.
