If you have watched dramas like Joy of life, Story of Ming lan etc. you will like it but wont enjoy it as much as enjoyed them.
This drama gives the exact feeling which you get while watching Game of the throne you start watching LOTR. You understand that this drama started the trend of cunning plot genre with badass characters. You will be lucky if this is included in the first few C dramas you watched but if if you have already watched later dramas which were inspired from Nirvana in Fire than you will not get that same joy.
Points that were best in this drama
Acting- specifically the guy who was playing the king, I watched his scenes many times on repeat he is such a good actor. Although I didn't like the acting on only character which was mother of Prince Jingyan the consort Jing and annoying chinese dubbing made it more unbearable.
Plot- Plot is the main thing in this drama which is the reason it inspred many other later dramas.
No Romance- I liked it that creators dared to make a drama with barely any romance in a time where Romance was very important part in the dramas.
