I didn't really know what to expect from this one apart from evil plants, so enjoyed the thrill of discovery as the plot slowly unfolded in the early chapters. It surprised me that there was so much of the plot focused on the issue of everyone going blind from an unrelated source before it got to any significant story about the carnivorous plants.
It did help set up the end of the world situation though, and showed much of the moral dilemma involved with deciding how much to help others in an unprecedented situation and whether your own survival would be compromised.
I'd class this as a Dystopian novel, though the man-eating plants do lend a Horror aspect. More of the plot involved survival in difficult circumstances long before the plants feature significantly.
There were times I wanted to shout at the characters "Why don't you..." or "Why haven't you..." and get them to do a few obvious things to improve their situation. I even wondered why it had become such a classic of Horror because much of it was more tame than I had expected. It wasn't what I expected at all, but it still made for an enjoyable read.
