i started this cuz i watched the actress in 'the double',
70 episodes is longg but i Enjoyed it (for a person who doesnt like 30/40+ episodes drama)

spoilers :
- FL did a gud job in acting; shz quick witted,
i felt in the starting 20+ episodes she was too obsessed with revenge for her sister's death & it was too exaggerated, also she is always saved by the empress/ fuheng/ emperor(unknowingly) which in reality doesnt happen everytime ; nonetheless i liked her plots n schemes for her revenge whether its for her sister/empress/for fight against other concubines n consorts.

- xu kai(fuca fuheng) role was short, but his story wid FL was amazing, their romance should have been explored/shown more;
he ditched FL first i get it so FL avoids any kindof interaction btwn them, but his love for her was until his last breath which is truly hard to see in a palace cdrama (without any expectation/response frm FL).

- Emperor was easily swayed along for eg: doubts regarding his birth mother, his concubines/consorts, various plots n schemes(imo);
also with whoever he was infatuated with at that moment/situation like in the case when he supported FL regardless if she was wrong/right (he loved FL unconditionally)

- empress/ex empress/ fuca rong yin ruled justly, loved the emperor but didnt receive his love, faced too many tragedy's regarding her offsprings, also her role was short i feel

- chunwang & FL relationship was good, they understand, depend on each other
his revenge for his birth right was ok but there no need for him to go plotting n scheming against her.

Summary :
the drama was good with its plots n each actor played his/her role well, their stories were worth watching
highlight is obviously the FL, her story

Rewatch :
i would watch it again maybe, to understand subtle details, schemes right from their start

-> to those who are contemplating whether to watch or no :
Just give it a tryyyy, & decide for yourself to watch further or no
