Halmeoni was annoying at first but after a slight lens adjustment, perspective towards her changed. That is what the director wanted me to know when I was watching this film, and it was successfully done.

The introduction of Mal-soon halmeoni was rather unpleasant. She is shown as someone who is rude, crass, and even arrogant. Later on, her daughter-in-law is not able to tolerate her attitude and was admitted to the hospital. Halmeoni realized that maybe she is a burden to her family and wanted to escape it. This is the reality that is currently faced by our elderly. I actually liked the transition of the first scene which defined ageism by the halmeoni's professor son then towards the scene with halmeoni and her family situation, then went to a point that she may be sent to a home for the aged. Because of that, she wants to be given another chance at life which was granted...with a twist that she returned to a 20 year old lady physically but mentally still her.

Now that she has returned to a youthful appearance (she changed her name to Doo-ri), she is now able to pursue her lifelong dream, which is to become a singer. Comedic scenes were abundant here and all did not fail to make me laugh out loud. Her feisty grandmother stature was ever present despite being in a 20-year old body, which made the comedy pleasing to watch, but what I liked here is that she is now able to minimize her previous crass character and somewhat evolve into a new character that is more understanding of her actions in the others' perspective without losing her unique character. Also, her being in a band with her grandson was not only hilarious, but the songs were just great and the lyrics and message were also fitting with the story. I actually thought the actress that played Doo-ri wasn't the real singer of the songs here, and was surprised and pleased when I found it out later on. She has a nice voice.

She is (almost) able to rekindle her romantic side as she developed feelings to the charming Seung-woo PD. I actually liked how she was able to reexperience romantic love, especially with after what she went through with life. Despite with a sad ending at that part, I still felt content with them both.

What I also found great in this movie, and personally, its highlight, is that it was able to explore more on the backstory as to why Mal-soon halmeoni became who she was. It was mainly to support her newborn son as she was now a single mother after the death of her husband that she had to create a stern, firm, and most importantly, a feisty person, in order for her and her baby to survive. I still find it wrong though how she did it, as seen on one scene. Yet to the unfamiliar person, she may be shown as someone who is rude, crass, and even arrogant, as I mentioned earlier. With that in mind, this is the reason why her neighbor and friend (and former servant), Mr. Park has struck with her all these years. I loved how the pacing of the movie slowly emphasize this side of her to me, the viewer, and at the end, I was able to understand our halmeoni, in an understanding as same as Mr. Park. I also admire that their "romance" was left open, and the final scene was just funny.

Plot wise, this movie is light in terms of emotion and predictable. But it did not fail to entertain me and bring comedy, it was just funny, especially on the "younger" Mal-soon/Doo-ri scenes. The music was delightful to hear, and the pacing as mentioned, was properly executed. There were some parts that I felt was conveniently ended (e.g., her relationship with her daughter-in-law, although to be fair, it has a time skip to a year later). I also wanted it to explore more on the "ageism" issue, as what was shown on the first scene, since it was fitting for our halmeoni, but somehow, they forgot to address said issue. Still, an amusing and entertaining movie to watch.
