If you´re in the mood for divertingly wasting your time in style (retro-style to be precise).
With a lightweight story, lots of action and some fun, too, this will perfectly do.
Its professionally done. You won´t regret it.

Other than that:
Too fast to be substantial or something that lasts or give something that remains. The focus here is on visual and acoustic effects. Storytelling is secondary. At least there was no saving on top-class actors. And, yes, they are in a good mood.

Recipe:
-top-class cast
-action with car chases
-hip scenery locations in the look of the 80s
-speed
-fancy retro styling - cool retro fashion (if you´re into it)
-all sorts of retro cars - styling and tuning (and noises, too)
-light and camera effects
-deliberately/supposedly ´cool as cool can be´

Final remark:
Never mind the drop of truth behind the backstory - corruption and money laundry in the context of the 1988 Olympics in SK. The bad (and good) guys could be anyone, anywhere. That's just the hook to give an interchangeable action movie at least a coating of its own: a Seoul-Vibe - here in an 80s retro look. (However, even this particular ´SEOUL´ Vibe shown could actually be anywhere - It´s more about an ´80s´ Vibe)

Overall, the movie comes across as a solid action movie production for an international audience.
Don´t expect unique Korean-style. (Except for the cast and their acting of course ... and even they can usually do much better, too...)
