I waited until I completed watching What's Wrong with Secretary Kim before giving my final thoughts in this review.
First and foremost I should mention that I overall enjoyed watching this drama and never once considered dropping it. The story itself is nothing new, but that's okay! I personally love a lot of the cliche genre's used in this drama including rich man "poor" woman, office romance, male lead falls in love first, arrogant male lead, and etc. The biggest reason from the story that really stopped me from considering this as one of "the greatest" rom-coms was how useless the character of the big brother (AKA the 2nd ML?) was, and I blame that entirely on the writing. He was for sure the most confusing nonsensical character period! Having said that though the saving grace of this entire drama for me was Mr. Yang and Ms. Bong's romance it was not only funny beyond words, but it was also incredibly cute to watch go down, this is one pairing I would not have minded getting more screen time.
The acting was incredible both Park Seo Joon and Park Min Young delivered in making me root for this final pairing. As well as all of the supporting cast, not a single actor comes to mind as the "weak link" everyone's performance truly made the cheesy lines (thanks again writers!) appealing and interesting to watch!
Music was always perfectly timed and the song "It's You" was perfect for romantic scenes.
Now as for the rewatch value personally a drama would have to completely blow me away for me to ever consider rewatching it, which this one didn't. I might look up specific clips that made me smile when I saw them, but no this drama is not one that I'd rewatch.
