For an interesting story, I'd go with The Hunger Games. For better writing, I'd go for Harry Potter. If you're doing some kind of character analysis, go with Harry Potter. It has 更多 character and they do more. If you're doing some kind of political/society, i'd go with The Hunger Games.
If 你 want to watch a good movie, I'd watch Hunger Games. If 你 want to read a good book, I'd read Harry Potter If 你 want to hear a good soundtrack, I'd listen to Twilight's.
That's basically how I see it :) I 爱情 Hunger Games and Harry Potter equally. If it wasn't for Mocking 松鸦, 杰伊, 杰伊 · (which, was a huge disappointment :/) I would have chosen Hunger Games.
