On the surface we can see some similarities between both stories. They are both about teenagers going into their senior year of high school, that maybe why the target audience is teens and young adults. Even some of the story lines are set up very similar with a new kid in school and boy staring at girl across the room. When girl gets cut or is bleeding boy has to make sure he doesn’t take a bite out of her. Both of these stories have been turned into major motion pictures/T.V. shows and have been very popular.
A big similarity starts to emerge from both stories. The fact that they are both vampire/human love stories with complicated love triangles. In the Twilight series the love triangle is between one girl who is human and two guys which are not so much human as is the same for the Vampire Diaries. However even though they seem the same on the surface they are really different story
