If I were a publisher, though, I’d hire the best critic I could find and have him or her write two reviews: a short one, to be printed the day or week the movie opens and that gives away little of the plot but tells readers whether it’s good or bad (the service aspect); and a longer, more in-depth review that discusses the entire film, to be posted online (the critical aspect). Then I’d put a message board beneath the in-depth review and sit back. Most people don’t want to hear about a movie before they’ve seen it but would love to discuss it afterward. Boy, would they ever.
