I’ve mostly been ignoring the various “rules for reviewing” posts that have appeared over the past year, but David Louis Edelman has managed to come up with a set that makes a lot of sense without being unduly prescriptive. The only one I think doesn’t belong on that list is the “no spoilers” because that’s so difficult to define. I’ve seen people who claim that mentioning what the jacket blurb says counts as a spoiler, and equally there are some books that you really can’t write anything sensible about without including spoilers. The other 9 rules, however, are pretty much spot on, especially #6.
