I thought it was a bit too sappy at times (don't all Korean dramas tend to be?), but it was overall funny and cute, and quite enjoyable. I felt the boys, specially Ji Woon, took a little while to grow on me, but they all eventually did. All actors were quite competent too. It looked like Park So Dam struggled with some scenes, but it didn't ruin anything. Some characters were terribly annoying, and I suppose not everyone's ship will make it to the end, but I promise Ji Woon's smile eventually wins over any heart, making up for any couple you might hope would never happen.
A very likable trait of this drama is that it keeps negativity to a minimum. Even the antagonists who plot against Eun Ha Won or the Kang cousins aren't the overly cruel sort and even they find their own balance eventually, making this is is really a great option for everyone who might be looking for a very light-hearted romantic comedy. The show has been fairly compared to Hana Yori Dango, and though I think plot-wise things really are similar, Cinderella and Four Knights still stands on its own, besides having less of a comedic focus than that other story does. This is mostly a show to make you smile rather than to make you laugh, and I think this is a very pleasant watch I'd recommend to most rom-com fans.
(At the date of this post, the show has been freely and legally available at DramaFever, from December 24 to January 2nd, 2017. There's still time to catch it in case you aren't a premium user already!)
