It wasn't just a drama; it was a rollercoaster of emotions with just the right amount of humor and a perfect cast.

Kim Soo Hyun and Kim Ji Won were the perfect leads for the drama and the best couple; they deserve an award for their acting. I wouldn't even be surprised if they announced that they were a couple because their chemistry was soooo good.
Park Sung Hoon perfectly portrayed THE anti-hero; I think everybody hated him just because his character was so detestable (It just proves that his acting is good and I agree).
QOT was so well-written; every little thing had consequences, and the screenwriters really played with us!
And the OST... even after finishing the drama, I just want to rewatch it; please take me back to Queens Mall!

There's nothing negative to say about this drama; I completely understand why it had such a large audience.

I might have wanted a bit more explanation on certain things (such as Mo Seul Hee's origins and motivations on the Queens family, etc...) and especially more scenes on the different couples like Hong Beom Ja and Young Song, or even on the spouses of the ML’s brother and sister...
