I've seen 3 eps of love like the galaxy and it feels slow..when does the story pick up?
It's not that good imo, most overrated cdrama for me. The best part about it is the fact that the emperors, his wife, and his sons are all good people. But at the same time I think the pace is too slow, it always have draggy moments where story moves slowly, and the FL is really annoyingly flawed character for me. If you watch for the actor and actress (Leo Wu and Zhao Lusi), better just watch The Long Ballad.
If you want a new costume drama you should try Royal Rumors, I like it so much more, really enjoyable to watch. FL is very strong, very intelligent, not naive.
Speaking of which, if you hate slow pace, better avoid most of those >30 ep dramas, those are often very slow and draggy, try watching dramas with <30 ep, like for example Reset has low episode count and the story moves at a fast pace and engaging.
