The movie itself is well thought out and there is a plot with non stop action. A good Korean cast that pulls off the acting really well. However.... at some points of the movie you're just like HUH?

Firstly the acting by the non-korean actors is just so mediocre and ruins the movie's suspense.

And secondly some may like the camera work but it's honestly too much at some points with really unnecessary angles and POV's.

Also very shoddy CGI that is so obvious at times.

Expected much better from a netflix show.

But overall it's a decent one-time watch in my opinion.
