I love this show. It is such an emotional rollercoaster with ups and downs. I truly fell in love with all of the characters on the show. My only note (just my opinion) is that they could've stuck to the way the book series went.
Spoiler!:
In the book, Stefan and Elena ended up together, as did Bonnie and Damon. I think that it would've been better to go in that direction. Also, I read an article that said that but, if they were it should've been done earlier. Knowing that Nina would be leaving the show. Stefan shouldn't have died It was very abrupt and unfortunate and there much grievance of mourning which was so sad!
But Overall great show I could watch over and over and over again.
