So, not super-duper problematic is just that I think the whole thing when she leaves everything behind, everything she knows (the Ocean) to run after a guy is problematic. Yes, she is a mermaid and that is what mermaids do, and in the drama, it makes sense and all, but, personally, I don't think anyone should abandon everything for someone, and having a drama with a plot like that, can, sometimes, make people think is a good decision to do so, like it is for love, so is alright.
But such is Dramaland, and with this comment, I am basically bashing almost the whole romance genre, and like I said I like this drama and have watched it two times ¯\_(ツ)_/¯.
Conclusion: There are some problems, but almost all dramas have some and it's okay as long as the viewers remember IRL is different.

Edited:
Though I like Legend of the Blue Sea I can't deny it has some problematic stuff, Ç_Ç' But nothing that the plot doesn't justify.

I am all for that 5th pairing!

where can I watch with english sub?

I just wanted somewhere for me to express how much I think Ji Chang Wook and Song Yoon Ah made a better pairing, by god, they were PERFECT together! Who was the one who stopped that? Man, this drama could have been a million times better if the pairing was Je Ha and Yoo Jin!!!!!!!! They had SO MUCH chemistry! Ugh!

I loved you post and agree with you about all of them, specially Jin Seo Mi!

I am really in love with this drama, In Na and Dong Wook make such an awesome couple! Besides, this drama is soooooooooo funny and fwa fwa love love~~

I strongly recommend Ming Lan!!

This ressonated so strong with me,,, Man, that first paragraph was ME.
Thank you for your amazing and sincere words

So... I am gonna watch this, but I will always bear in my heart that this synopsis greatly deviates from the novel, cuz Minglan is the most peace-loving kid in the novel, she does not want to avenge her mom, and she is very loved by her Grandma, and her dad shows her affection sometimes as does the Eldest Sister - who basically saves her life when she takes charge of Minglan's health issues - before she marries and leaves. So I think I will treat this drama as something completely apart from the novel,

I will be honest and tell you that I agree that first I love Yang Yang, but I do think that Zheng Shuang is not at all a good match for him, all the romantic scenes where always kinda of spoiled by her stiffness,if Yang Yang was kissing me I would be jumping him no matter how shy I was!!! And I say that I like this drama, because I like the novel and the slight danmei (yaoi) content it has, it satisfies both my honey desire and my fujoshi desire.
P.S.: I get pissed off by the chauvinist/sexist stuff in the dialogue even when Yang Yang says it, I know it is a reality in China - that people are way more sexist there than in the ocident, but it still pisees me off.

He was super cute in Oh My Venus
