Watched this drama because of previous recommendations. For me it didn't meet the hyped up expectations. Had to fast forward parts in episodes 15 onwards. FL's character was frustrating. IU's acting was at times hard to watch. The later storylines felt like it was a mish mash of trying to put things together so that an ending can be made.

The political back and forth is to be expected as its based in the palace but there was too much focus on FL non action than other character stories. The love triangle got tired.

I've decided to do a pros and cons based on my opinion:

PROs
The Princes - nice eye candy
Lee Joon GI - good acting and eye candy
Costumes
Quality of Actors - experienced actors who were able to portray believable characters

CONs
Lengthy drama - could've stopped at 16 episodes
FL - IU's acting - not good
