I have to admit, I quite enjoyed Red Queen. There were a lot of interesting and engaging aspects to the plot, characterization and world-building that I thought worked well. It is a fairly fast-paced novel with plenty of intrigue, plot twists that keep you turning the page (although probably won't blow your mind if you're paying attention), as well as a healthy dose of romance for those so inclined and some exciting action sequences. 
 It is, however, unusually over-hyped for what it is, if I'm being honest. It doesn't bring anything particularly new to the fantasy-dystopia genres and there are definitely plenty of similar books out there that have done it all before (and in some cases much better). If you read in these genres a lot you will have a reasonable idea where everything is going; dystopian society divided by class, subjugated 'commoners', elite ruling class, rebellion, special powers and one girl with unique abilities who threatens to change everything. It's kind of like The Hunger Games cross Game of Thrones, but with magical powers. I'm a bit bemused as to how this particular book got so popular when other similar novels remain largely unrecognized, but hey, that's how it goes I guess. Still, I'll be keeping an eagle eye out for a sequel. Not sure I'd pay to see a movie version though.
