In Fantasy (and other fantastic genres) literary theory, is there a more cited and critical writer than Todorov? While many of his groundbreaking theories have been, now, reconsidered, rejected or reworked, his structural approach to the fantastic, in particular to do with the cognitive response to the marvelous and the uncanny, is still at the heart of fantastic genre theory. Anyone reading Attebury, Wolfe, Clute or Mendlesohn (among many others), will inevitably find themselves returning to Todorov at some point as the basis for study, even if they later move to more modern theories.
For non-research readers interested in genre theory, I am not certain how useful and understandable this book might be. It is important to be aware that many of his theories have been modified or have evolved into better structured concepts, implying that for the novice or amateur, more recent genre studies might be more helpful and appropriate. In addition, Todorov's style can be at times convoluted or needlessly complex (and despite his claim to 'structuralism', he does diverge from it). That said, his ideas still come through with surprising insight, and, as said, is invaluable to any and all genre theory researchers.
