[OK since no one really reads my reviews, I'm gonna write as long as I want, nobody cares!] 
 [?]Likes: 
 * Characters (Usually everyone in a story has the same personality as the author. But this book had different types of people which was cool!) 
 * Storyline (it was pretty complicated and therefore it was really awesome!) 
 * Some ideas (many big ideas or small details in the story that made it wonderful) 
 * Writing style (so friendly, and sometimes funny) 
 * Atmosphere (London, an old castle near a mysterious forest, where people learn magic... It's no wonder lots of people love it and many authors have tried to write a story like it!) 
 [?]Dislikes: 
 * Harry's character (honestly, I couldn't figure out what kind of a boy he was. Sometimes he's a loser who runs away from the bullies, sometimes he's a hero everyone expects him to be, sometimes he's afraid of saying a word, sometimes he dares to fight Voldemort...) 
 * Plot holes (I think there's no need to write about the many big black holes in the plot!) 
 * Wizards' world (I expected the wizards' world to be different. I didn't expect them to educate in schools like the real schools, or play basketball on brooms, or play chess with alive pieces, or have a ministry, or hospitals or a bank. Everything was like the real world with a little difference. It wasn't magical enough.) 
 * Muggles (this book tells us that magic is so cool, and Muggles are useless and dumb. And I, the reader, AM A MUGGLE! It's just insulting me!) 
 * Long chapters (the chapters weren't exactly loooong, but I couldn't read the story as fast as other books for some reason, and every time I checked how much more till the next chapter, and saw OMG there's still 10 pages to go!!)
