Compared to TVD and The Originals, this show didn't reach my expectations... But... there are a lot of wonderful characters like Ric, the twins and above all Hope Mikaelson. I didn't like Hope in the Originals but she had great character development in this show. Another great character is Lizzie Saltzman, she is feisty and humorous. She is a lot like her aunt Liv Parker. Also, for Damon Salvatore fans... there is a new character Sabastian. He has the potential to be the Damon of Legacies.
There were also a few cameos of characters like Jeremy Gilbert, Matt Donavan and the best: Freya Mikaelson.
And I am pretty sure we can see rest of the Mikaelson family or maybe Bonnie Bennett and Caroline Forbes in the upcoming seasons.
