I find it harder to write reviews for short stories and very long stories. The “sweet spot” seems to be 150-400 pages. Outside that range, it becomes more difficult.
Short stories are hard because of the desire to avoid spoilers. When everything happens in few words, it is hard to avoid giving everything away while still conveying a full picture of the story and its characters. Quite often, there isn’t enough story to really get a firm opinion for everyone and everything. I usually end up with a feeling that either I wanted more, or I didn’t.
Long stories are hard because there is just so much of it. How can you give an overall impression when there is so much room for plot twists and character growth. I find that it is hard to narrow my review down to just a few points. Doing so means I ignore huge parts of the book in my review. Since I don’t tend to write really long reviews, this results in a review that I feel doesn’t adequately over the book as a whole.
What about you? Do you find it hard to review short or long books? What’s your length sweet spot?
