The korean actors were good. Those who portray the americans.. very lackluster. The main actor has a hot body.. likin it sooo much. The movie was like some cutscenes in a video game.. at some point its like taken from a 360 or go pro action camera. The story was okay.. generic stuff.. virus and cure la la la. the stunts were brilliant with a lot of gore which i like. Though i must say, i got feverish after the neverending fight scenes. You need to rest like every 30 mins... the camera work was damn too much.. very dizzying. Netflix...... we have a problem. You got to amp up your originals. C'mon Netflix.. wake up, back to the drawing board. Give us Quality.
