As a younger adult, I am able to relate with this show and the lives of the teenagers in it. Charismatic characters like MG and Kaleb are a joy to watch, and Landon with his deadpan deliveries and budding emotions stand out in the sea of other teenage personalities. Hope is a strong and likable lead, but she acts too much like an adult, even if she is powerful.
There is a strong theme of honesty in this show, or rather, the lack thereof. Almost all of the main and supporting actors have lied multiple times. These lies and/or the revelation of truths are constant plot drivers and climaxes of every episode. Some of these lies are unnecessary and exaggerated, and it breaks the immersion of the show as you tell yourself "that doesn't make any sense." Even though "Legacies" takes place in a fictional world, the human parts, like dialogue and decision-making, are unbelievable as they would not normally happen with regular people.
This show is good, but fewer lies and relatable dialogue can make it great. One of the reasons its predecessor, The Originals, is so great is because it was often no-nonsense and straightforward. Even though the age gap between the characters of both shows numbers in the thousands, that does not excuse the inauthenticity of character interactions.
