The writing is basic at it's best and after the only big reveal about the mysterious villain, half way into the film, Mission: Cross literally is devoid of any intriguing moments and the action too is quite generic to stand out. All it leaves is the two main leads to kick up the spark and the comic timing to salvage what's left but that just proves to be not enough. Even with the runtime of barely 100mins, the film gets boring and the half baked screenplay doesn't really offer anything to remember. Spoiler, the film does end on a note opening up for a sequel but there is hardly any interest left to care for it.

The strength of this action comedy is that it follows the formula with various cliche moments -- the couple's witty banter during a shootout and a car chase involving large trail trucks -- meaning that laughs are guaranteed. Like a popcorn flick, the flow is seamless and natural...

What elevates this movie's delightfulness is the weighty presence of veteran actors Hwang and Yeom... This the character audience has been waiting for from Hwang. He proves that he can not only digest such a role but also make it look special on the screen while Mi-seon, for her part, shows a flawless action sequence, and Yeom, using her long arms and sleek moves, performs acrobatic jumps and also shoots guns skillfully...

The couple's witty banter during a shootout and a car chase involving large trail trucks meant that laughs are guaranteed...With rest of the characters doing justice to the role "Mission cross" is a guaranteed weekend entertainer...

Keuroseu or mission cross is a netflix orginal korean comedy film. I think it does very well and actually mixes comedy well with the crime elements. It has a pretty good cast that all work well together and the action elements are both fun to watch and funny, especially when the detective uses her knuckle taser. This film focuses on a couple, kang mi seon the detecitve and her husband park kang moo and she does not know about his previous life, so while investigating something major its not long before the unlikely heroes team up to protect one another in the ultimate test to their marriage. This was overall a pretty fantastic film.
