I found this movie at Blockbusters in the DVD section. Although I am of Korean background, I have not heard of this movie prior to finding it at Blockbusters. I rented it out of curiosity... the short description on the jacket seemed interesting enough. I only found out after watching the movie that it was such a big hit in Korea a few years ago. Watching the movie, it reminded me of "The Rock", "La Femme Nikita/Point of No Return", and "Heat".. All these were previously mentioned in other comments, and I agree that some of the scenes in Swiri (or Shiri) weren't very original in that regard. Still, the quality of the movie was surprisingly excellent. I also agree a lot of the action sequences in this movie weren't perfect, but then again, so are some of Hollywood's action movies. Some of the special effects were below par as well (the scene where a building blows up wasn't too convincing). Still, I've seen other Korean movies and I must say that Korean films have come a long way.. cinematography, plot, characterization were all done really well. I watched it twice.. once in Korean audio without subtitles, and again with English subtitles. The subtitles, although done very well, does leave out some of the subtleties. I'd say it is a difficult thing, translating dialog without losing something somewhere. Still the acting does fill in the blanks quite well I thought. I thought the acting was excellent.. Knowing a bit about the North/South Korean history would help understand the movie. Also knowing a bit about South Korean perception of the North Korea would also help understand the movie better as well. I thought that the love story in the movie, although it is a type that is very very often used (the tragic type) especially in Korean films, worked well. I thought it was far more convincing than the love between Anakin and Amidala in SW2 AOTC.
Overall, Swiri/Shiri isn't perfect. It isn't without holes. It doesn't compare to Heat (an excellent film). But unlike some of other "Hollywood" movies, that Blockbusters had many more copies of (Black Knight, Joy Ride, Thirteen Ghosts), I was glad to have paid $4.09 to rent it for 5 days. That reminds me. I'd better return my copy since they only had copy. If you can find a copy at your local Blockbusters or a DVD/Video rental place, rent it.
