I really didnt like it.
Maybe it is because iam not female.
But i have the impression that the only reason this show is so popular is that a average not special girl is worshiped by lots of guys who are seen as very attractive by lots of woman
because yona is so generic lots of girls here can relate to her and thus can imagine that they could be saved and worshiped by young athletic bright handsome guys too

the most pathetic parts in the story are those who try to portray yona as a strong and independent woman
she is a princess, she is the dragon and so on
all things she is just born with
she gets protected all time by crazy strong guys
but yeah she is such a strong independent woman

this show is just a girlfantasy
"yeah i would like to be a princess, the chosen one, the dragon who is surounded by handsome strong guys who do everything i want without me having accomplished something by myself"
