A Great and Terrible Beauty (Gemma Doyle): Victorian schoolgirls and Wicca! In a nod to historical writing, the author avoided actual research and threw in lumps of racism instead.
Animorphs: If you don't already know, I'm not sure what to tell you. People morph into animals to fight brainslugs.
Battle Royale: The original childmurder games novel. Recommended.
Chosen of the Sun (Exalted): The first Exalted tie-in novel. Full of setting confusion, too many characters, and a plot revolving around finding the legendary +1 sword.
Darkest Powers trilogy: Chloe can see ghosts and do other necromancy things! The plot crawls along about teen drama instead and eventually lurches to a stop without resolving anything much. Bonus mental health failures abound.
Divergent: Set in the blasted wasteland (?) of Chicago, civilization has split into five factions but the main character is divergent (?) which is bad because she fits into more than one, or can hack simulations, or isn't controllable, or something. Also, everyone hates Abnegation just as much as Abnegation hates prosperity and joy, but they should still totally run things. The movie improves on some of this at the cost of problems elsewhere.
Fate/Stay Night: The famous visual novel, with great female characters...and a protagonist telling them to get back in the kitchen.
Fault in Our Stars: Pretentious pretentious pretentious pretentious. Pretentious? Pretentious pretentious.
Graceling: Well meaning attempt at a feminist message that mostly revolves around guys and is full of terrible attempts at characterization, with bonus research fail. Also demonstrates that no matter how simple and straightforward a magic system, authors can still screw it up.
The Host: By the author of Twilight. Starts off surprisingly good, maintains it for another ten chapters or so, then takes a nosedive into Failureville where it crashes and burns.
Hunger Games, Catching Fire, and Mockingjay: The one that started it all. Recced to me due to feminism and worldbuilding, contains a nonsensical world full of basic research failings with a murderhappy protagonist forced into a relationship where she's constantly criticized for not loving him back enough. The first movie is an improvement, and the second even more of one.
Legend of Korra: How quickly can the sequel to a beloved show destroy all my goodwill?
Matched: In a poorly thought out dystopia with all sorts of problems going around in the background, the heroine just goes on about how in love with a boy she is. Its sequel, Crossed, has all of its many flaws and not one of its few virtues.
Pokemon Black and Pokemon Black 2: A new generation of pokemon, with an absurd plot, a tutorial mode that lasts most of the game, cutscenes that will not end, and constant usurping of my spotlight by Douchy McFlamehair.
Pokemon Blue: The first and best! A run through of the original game and all the million things the players back then believed, in the original colors.
Pokemon X: A huge leap in graphics, minigames, cuteness, and being brain-meltingly easy.
The Reconstruction: A game that claims to subvert expectations, with mixed results. Very story heavy.
Unwind: Pro-life apologism mixed with organ donation mixed with all-purpose author incompetence. Bonus rape.
Wither: In a future where people die young, women are kidnapped by rich men for wives in a way that is definitely not rape at all. And raped thirteen year olds are worse than rapist kidnappers. Fever manages to have even shoddier worldbuilding and jam in more (and younger) rape.
World War Z: Recommended to me as a realistic take on the zombie apocalypse. Is anything but.
Attack on Titan/Shingeki no Kyojin: The best and most interesting horror comes from things that are inexplicable and people that struggle to understand them.
Big Bang Theory: is a terrible show.
Bionic Heart: What's wrong with dating games for guys.
Broken Sword: Shadow of the Templars: The Director's Cut: This game is incredibly bizarre in that it is both wonderful and awful in quite literally alternating intervals.
Cinders: Feminist Cinderella visual novel!
Clannad: When it's good it's very very good but when it is bad it is horrid.
The Crooked Man: Pretty amazing freeware game.
Crossed (comic): What you need to understand is comics can be vile.
Dear Esther: A first person ghost story.
Defender's Quest: RPG story style tower defense.
Delirium: Somehow manages to be agonizingly boring despite its horrifying setup.
Eon: Rise of the Dragoneye: Asian flavored fantasy that starts good and ends terrible.
Erfworld, Fate, and Poor Planning: Discussing some (very bad) plot choices.
Fatal Hearts: A visual novel with vampires, impossibly hard minigames, and nonsense choices, oh my!
Fey: A neat little action adventure game made in RPG Maker 2003.
Hatoful Boyfriend: Pigeon. Dating. Sim.
Heroes of Might and Magic: An in-depth look at the tactical RPG series.
Hierofania/Hierophany: A visual novel of quality.
I am a Hero: Zombie manga with some unconventional choices.
Ib: Very well done RPGmaker puzzle/horror game.
Immortal Defense: Unusual tower defense game.
John Dies at the End: Why I am not going to read that far.
Kara no Kyoukai/Empty Boundary: A supernatural-noir-hardboiled story about badass women.
Last Scenario: A somewhat unusual, intensely difficult RPG.
Logical Journey of the Zoombinis: Fun kid's logic game. The sequels are less impressive.
Long Live The Queen: A princess raising sim where one wrong move gets her killed.
Mad Father: A well-polished horror game that's a mess of bad design decisions.
Mermaid Swamp: A gruesome and disturbing horror game with a lot of clever ideas, but comes to a lackluster ending.
The Mirror Lied: An extremely short, very intriguing and well made game with a poor ending.
Misao: Short horror game where just about everything kills you. Decent plot.
Mortal Engines: Moving cities that devour each other. Just go with it.
OFF: A well done game overall with a fascinating setting but fumbled conclusion.
Oz the Great and Powerful: Why this movie is a stain upon existence.
Pokemon X & Y: Posts involving sexism in the games.
Quick recs: Because you need quality in your life.
Seeds of Wither: A short story with Rose, set before Wither begins.
Skyline: What alien conservationists would look like.
Spirit Engine II: Extremely difficult RPG with interesting mechanics and characters.
Star Trek and Superman movies: What did they have in common? Disregard for human life.
Stolen: A brief look at just how terrible the YA genre has become.
Telepath RPG: A well written RPG with interesting mechanics.
Temeraire: Dragons in the Age of Sail.
Two and a Half Men: Worse than Big Bang Theory.
Undertale demo: Amazing.
The Void: Gorgeous game with a weird story and some unnecessary nudity.
The Witch's House: A generally solid game with a lot of clever bits, but hampered by sticking to certain game conventions that don't work well in it.
WWZ the movie: Nothing much to do with the book, but pretty good itself.
Also, there's fanfic. For Hunger Games, I wrote Fox Games, where there's no clause about needing your district partner. For more on the subject, there's also Zero Sum by Ember Keelty. And Act is working on a complete rewrite, The Hunger Games: A Retelling. I also wrote a Wither fanfic about advice for daughters in the world.
If you enjoy the idea of Let's Reads, you may also like Reviewing Rowling, doing Harry Potter and the Sorcerer's Stone. Dodging the Anvil is another hate-based blog currently doing The Taking.
The RPG.net forum also has a number of threads on the subject. I particularly enjoyed the reads of The Death Gate Cycle, Marvel's Civil War event, and Gor.
