THE ACTING:
**The actors delivered lines well, emoted properly and consistently, and looked good doing their job. I have nothing but praise for the acting in this drama. The reason I watched this until the end was because of the actors.
**My favorite character was He Le (Du Hou Jia)....he was so much fun. And his final scene had me in tears.

THE AESTHETICS:
**The locations were beautiful, even though some of the office scenes were over-the-top
**The wardrobe department did a fabulous job. I loved all of the outfits, shoes, jewelry, etc., and for the most part, they fit well. (That dress that Bai Bing wore would have been perfect without the corset-styled bodice....it wasn't flattering.)

THE BAD:
**The English title is misleading. I originally clicked on "The Girl Who Sees Smells" because that's an actual thing, and it is interesting to me. This was not about seeing smells however. This was about a girl who had outstanding gustation (taste.)
**The directing and editing was pretty bad. There were scenes where I could see that the actors were following direction instead of acting naturally. I blame this on the director and not the actors, because multiple takes are often needed in order to get a natural shot. But when whole groups of people are standing there, just staring and not reacting to a character's actions or delivery.....and then they put the scene in slo-mo.....it's bad. Often, in my head I could hear the director saying, "When she finishes her line, turn to the left and walk away" or "Pretend you're talking amongst yourselves in the background while she is speaking." It was just SO obvious to me.
**Scene transition was jarring. Suddenly you're in a whole new scene. Did they not have an editor??
**The plot. I mean, honestly. They could have come up with a better premise than 'rich boy ages backwards, poor girl's kiss cures him.' I might have liked it if it hadn't been in a real-world setting.
*The tropes. Don't get me wrong, I kinda love tropes, but a girl can only twist her ankle so many times. Even in the story, the ML goes, 'why aren't you wearing the flat shoes I bought you?' He knows. LOL
**The ending....I mean.....

I wanted this to be good. I watched the whole thing, and gave it every chance. Props to whoever cast this. The actors tried.
