I'm not going to lie, my main reason for wanting to read this book is that I really enjoyed the movie. And after reading the book, (I'm going to put this in writing, be prepared, remember this day), I perfered the movie to the book. 
 The book was alright, it had some great moments - I particularly enjoyed the flirting between Daniel and Bridget, and her mother's straight up insanity. However, it felt like many of the characters weren't completely fleshed out, which is v. bad (as they say) when one of those characters is our Mr. Darcy. Also, the shorthand got bothersome very quickly, despite it being something I do all the time too. It wasn't so much the abbreviations that bothered me though as the incomplete sentences. 
 So in the end, I perfer the movie. Renee was able to bring some charm to Bridget that didn't make her seem quite so inane and desperate. I think the book relies more on friendship rather than romance, which is really good. I liked it, but it could've been better imo (in my opinion).
