Some parts are hilarious, while others ventured off into such bizarre randomness that left me going "WTF?" The start is absolute dynamite (the part about the hand buzzer!), but my attention wandered a bit in the middle, maybe because I haven't actually read the original, so some remarks might have gone over my head. (I'm aware of the infamous tampon scene though, and the repetitive "long fingers", and how she keeps on tripping and doesn't have e-mail.) Even so, there was still enough material for someone who hasn't read it to find this book funny. What is amazing is that the author was able to sustain a parody of this length. It also doesn't go on for too long, thankfully. Just when the energy starts to flag, the pace quickens, and we're soon ushered into the ending before I can let out any groans of complaint.
There is a lot of text-based humor (a few times I had to make a mental "I see what you did there" hat tip to the author), but there is also so much physical comedy here that I kept on imagining this as a movie, like "Vampires Suck" did for Twilight. I wouldn't mind if they used this as a basis! I'd watch that.
