This is probably one of the worst Korean movies I've seen. It feels like the production is rushed, and it looks like a TV series episode (a low budget one).

The story is bland. A great movie has to have subplots, but this one is so simple, it can be told in 20 minutes. There were so many holes in this movie, and there are scenes that are not supposed to be funny, but you'll chuckle out of disappointment.

I wasn't sold on how Mrs. Cop was still that strong and agile in 2018 as she was in 2002. In the present, she only had a desk job and complained about balancing work with motherhood. One of the thugs even asked her if she lifts weights because she's surprisingly strong. A scene in their house shows a stressful environment, so it's just not believable.

The acting of both leads is ok, but there was no chemistry as in they don't compliment each other. The brother's acting is lazy. I know he's supposed to be "slow", and that trait is also supposed to be comedic and adorable, but he achieved neither.

The editing is terrible. Plenty of mistimed and unneeded cuts and poor camera angles. The mall scene is a testament to this.

I feel scammed by its 8.1 rating (as of writing), so I now have trust issues picking out a movie on this site without reading the reviews first. I will definitely never rewatch and won't recommend this to anyone.
