Eternal Love was a decent drama. Just middle of the road. A good watch if you're bored, but nothing spectacular. The issues I had were the two main characters. I honestly just didn't care much for them. The Emperor Dong Hua character, I found myself more interested in him.

Su Su: Mortal identity of Bai Qian. She was extra needy, extra clingy, and cried majority of the time for her man.
Bai Qian: High Goddess in the heavenly realm. She turned into a mean alcoholic in the third act of the drama and she pretty much abandoned her child.
Si Yin: Alias of Bai Qian when she was the disciple of Mo Yuan. Essentially she was a teacher's pet who got a free pass because the teacher had feelings for her.

Mo Yuan: He was okay, but not really memorable.
Ye Hua: I didn't like how he treated Su Su once she was in heaven and when he reunited with Bai Qian, he just turned into a simpering love struck fool.
