I hate the Half-Blood Prince. Too much useless teen romance (actually this applies to 4 & 5 as well), Dumbledore, the greatest character in the series, dies, Dumbledore dies...
Snape: Hey, master, you're a cool lich necromancer, right?
Voldemort: Yes.
Snape: Then why are you always getting your *** kicked by teenagers?
Voldemort growled and made no comment.
Also, Quidditch, the "Chosen One" sounds like something out of a pokemon movie (remember how Ash had to save the world from the rampaging pokemon? I don't know why I watched that),
If there is an evil necromancer threatening the universe, why is most of the book focused on teen drama? And isn't it a coincidence that Snape, whom everyone hates, goes over to the dark side? And why are the zombies called Inferi?
