Sooo... yes I did compare it to the drama. How could I not? I’ve already finished the show so there is no way I could not compare them.

The story was definitely rushed as a lot of things are explained later or in a weird flashback that lasts for around 4 minutes. When watching it, I found it amazing how they condensed 4 episodes into 10 minutes for the movie. I originally thought that they would cut some information (such as Mo Yuan and everything before that) but nooo. They just had to cram everything into the movie. And I mean everything (except for a couple small things).
I saw this from another review and I completely agree-- if a person had not watched the show before, it would be complicated and confusing to understand. For someone like me, who has completed the show, it would be easier. When I was watching the movie I always wondered where I was, I'd figure it out and then things would make sense. I suppose this is why I'm rating it higher than it should probably be.

The acting was fine, it was more of the casting that was my problem. I wasn’t a huge fan of actors portrayal of Bai Qian and Ye Hua. If anything I believe it was their looks that was the problem. They looked too young, considering they are supposed to be thousands of years old (Ik it works differently but still) you’d think that they would look a bit older. I’d especially highlight Bai Qian, 1. She’s older. 2. Her personality at the time the film takes place in was this strong woman who likes drinking, a lot. She also as this attitude of not taking crap from anyone. I could not see Crystal Liu as this woman. I fully believe this is due to the fact that she looks perfect for a role as a high school student in a romance drama. Not her fault ofc, I just would've preferred a different casting decision.

Not to mean that I wasn’t entertained. It was actually an interesting movie to watch. Would I recommend it? No. Rewatch it? No. But I didn’t think it was bad. That's why I gave it a 7 (a 7 for a movie is average in my books).
