YA novels, my favorite topic! As much as I love the genre, I'm not so biased as to not pick out the flaws. As Cinema Sins says, "no movie is without sin." Same goes for books, obviously.
The Selection, as iris, pointed out, had terrible world building; every effort to make it sound as terrible as it was was soon refuted as characters had open opportunities and wide access to luxury items. The politics of it was poorly implemented as well and a lot of the character's actions were foolish and unreasonable. The writing was rather plain, and they all had really stupid names. BUT it's still a major guilty pleasure of mine. And the covers are gorgeous.
I thought the Hunger Games was boring so I never finished it. I'm not big on the franchise.
Don't get me started on John Green. I only watched the movie to Paper Towns (I read TFiOS in eighth grade) and I hate Margo Roth-Spiegelman (why do they have to say her full name all the time?). She's a terrible character who thinks she's so special because she wears bomber jackets and readily points out the symbolism in life. Sometime in December last year I finished a book called "All the Bright Places," and if you don't like John Green, I wouldn't suggest it.
As much as I dislike John Green's writing, it is nothing compared to the Divergent series. In the first book, Tris had to keep pointing out her short stature after every single sentence. She called her fellow initiates "weak" when she was physically weak as well got beaten to a bloody pulp when sparring. Four was just arm candy, he had no personality. No one had any personality. The character names, while less extravagant than The Selection's, were so plain and boring. Jeanine Matthews doesn't scream intimidiation like Lorne Malvo. AND THE END OF INSURGENT MADE ME SO MAD. POST-APOCALYPTIC CHICAGO WAS A 200 YEAR-OLD SOCIAL EXPERIMENT?! THAT'S SO UNETHICAL AND SO UNNECESSARY. WHY, VERONICA ROTH? I didn't even read the rest of the series, I read some of Insurgent but I stopped.
I hated Maze Runner for the same reasons I hated Divergent, but to a much lesser extent. The plot was so boring and I couldn't get attached to the characters. My dad listened to all of the audiobooks in the series. Strange considering how much he loves Jim Butcher and anything that isn't YA.
Nonetheless, I for some reason love to read bad YA novels. It's a shame how there are so many books that have been snubbed during book awards. None of the books I like ever win, I have the worst luck.
