This movie is also available on Prime Video if you want to watch. This movie has a fine story line and it is interesting. It isn't rated much good on Amazon Prime Video but I kinda see why. The sound of guns didn't sound realistic. Very underrated American actors and I find that some of their acting was not excellent. The only acting that seemed real to me is the male lead and Heo Sung-tae's character Kwan Sung Woo. It can be rewatchable for me but only to see Heo Sung-tae's and male lead's good acting. I'm thinking the technology could be done slightly differently as well. The movie is very underrated as well but I think it's also due to these reasons of mine as well.
