I'm not fantastically well-read, but to imply that this book is somehow inferior (as one review has), because it makes use of such 'embarassingly conventional' techniques as PLOT, is kinda arrogant.
'Crime and punishment' is able to integrate the readers' logic with the emotive as a way to illuminate his philosophical preoccupations which are by no means trite. (And anyways, for Dostoevesky's time, the style of writing is far less elaborate than, say...Tolstoy or Dickens).
You can read this as simply a thrilling crime drama, but more than that, it delivers an essay on meaning in modernity. You may scoff at its end implications ( by all means, please do), but i believe it was written by a refined artistic mind--no post-modern cynic could hope to equal such an achievement. ever... so filled with smug contempt that the Literary Snob is incapable of producing anything with sincerity and truth.
