Vampire Diaries. It has 更多 action and conflict rather than twilight, which is mostly just love. I cant say for the books, because I tried 阅读 the vampire diaries after id seen the show, and it just made no sense to me so i gave up :P
Well if 你 are refering to the 图书 i would say that Twilight is definately better than the Vampire dairies. But if 你 are talking about the movies... well i don't know. VD is a amazing. But i like Twilight too. So i don't know. Maybe Twilight.
Does it really matter? Because, you're asking us which is better, like there is a fact one is higher than the other. When there truly isn't. It's all in a matter of opinion.
I 爱情 them both I really do but The Vampire Diaries I absolutely cannot get enough of. 你 wait a whole 年 to see a Twilight film and 你 leave thinking ahh yeah that was everything I wanted it to be, I'm satisfied for another WHOLE year. But The Vampire Diaries I think like this but on a weekly basis! I literally can't wait until the following week because they pack so much into one episode it's like getting a weekly film. Twilight I 爱情 你 but TVD I CHOOSE YOU!
