I'll say this: for the quality of the prose, it deserves its classic reputation. The originality of the theme by which I mean, a brutal deconstruction of petty, whiny twits is also worthy of great praise.

However, Madame Bovary is rightly well-known for a highly... unlikeable... main character, and so those with short tempers are advised caution when deciding whether to read this. In fact, nobody in the book is all that likeable, so you had better come into the book with a readiness to mentally MST their thought processes. (This IS in line with what the author wanted, since he wrote it to mock the bourgeoisie, so their unpleasantness is wholly intention.)

I'd recommend it. Now, for those who don't mind spoilers, read on to find a summary below:

( Bella Swan meets reality. It does not end well. )

The common assumption is that super-senses would actually drive people crazy due to super-stimulus, and that the authors are stupid for not taking this into consideration.

However, this neglects entirely the possibility that the condition granting the powers also grants the mental capacity to deal with the powers. Which seems a strange possibility to neglect when these conditions often include needing to drink blood daily or changing into a savage, feral animal monthly, methinks. A little change in brain wiring is THAT much stranger than furspolsion?

In real life, there are people who get overloaded by a NORMAL level of stimulus. (To be frank, my frustration level starts shooting up at an abnormal rate when somebody keeps nagging at me when I've repeatedly indicated that I'm busy and my attention span is VERY MUCH somewhere else. In all fairness, I seem to be homozygous for this.) That doesn't mean that everyone with normal-to-above-average ends up banging their head against the table in a crowded cafeteria. It depends upon whether their brain can handle that level of stimulus, whether its level of filtering out excess stimulus is sufficient, and how high their level of frustration tolerance is.

So I take it as a hand-waved superpower that werewolf/vampire/whatnot status automatically adjusts the brain to handle hyper-stimulating environments. Either that, or it massively readjusts WHAT the brain considers a hyper-stimulating environment. Some interpretations of vampire myth have vampires being repelled by garlic - perhaps it's less physical inability to go near and more "MY VISION IS RUNNING IN STREAMERS MY BRAIN HAS SHUT DOWN MY GOD WHAT IS THAT THING ...Garlic? *sighs* That fucker behind the church told me vampirism would CURE my sensory sensitivity..."
(Personally, nails on a chalkboard only mildly irk me. Crying babies? Shrug it off. Cardboard scraping against cardboard (or styrofoam) makes me physically tense up just at the memory. D| I'm not hypersensitive to anything, but my point is that the bands of ordinary sensitivity are not uniform.)

Now, if one wants to toy with hypersensitive vampires/werewolves/whatnot, go right ahead! That will be interesting! But it's obnoxious to swear that ANY CREATURE WITH SUPER-SENSES EVER will have to suffer from hypersensitivity.
