On slagging off other writers' books

This is the reason I feel critics are important. Science/speculative fiction has always been a little weak in the regard, as the critics are very often writers in the genre themselves, and it’s a smaller world than mainstream, so there’s more worry about toe-stepping.

Not that there hasn’t been some great literary criticism in SF, but aside from various best-of collections, actual criticism of contemporary work has always seemed hard to come by.
