Lucky Romance is your typical romantic comedy - a meet cute couple, best friends, overacting to draw laughs and hints of melodrama. And while it isn't the best romantic comedy out there, it also isn't the worst.
Like many similar shows, there isn't much plot beyond the romance of the leads who start off as polar opposites. There's some side plots, yes, but their purpose is to help move the romance forward. The plot is fairly entirely fluff, having little substance but entertaining enough.
The acting is average. Hwang Jeong Eum is great as always but falls into a common character type. Ryu Jun Yeol manages to take the character of Je Su Ho and make him endearing and creative when he would be dull on paper. He's the heart of the show. The rest of the cast are serviceable, being neither great nor terrible.
The same could be said of the directing, which isn't groundbreaking or all that creative, but does a good enough job telling the story.
Lucky Romance is average and can go on the rainy day/dry-spell list but isn't likely to win over any hearts.
