It's not that I dislike Elijah, he has just outworn his welcome like the rest of the Originals.
I also prefer season 2 Elijah. He was badass to me, scarier than Klaus really. When he chopped of Rose's friend head Slater? Can't remember his name, and then when he snatched the hearts out of those 2 vamps or when he rescued Damon. I loved that. But now he just makes random appearances that aren't really needed. I did like him in 3.13 I think it was.
