First of all this is my very first review so if it's not helpful for you, sorry in advance! I have watched this movie twice and some scenes of movie like more than 5times so as the part of Rewatch Value, I'm giving it 10 I believe that the whole movie has lots of beautiful and breathtaking moments which make the viewer more and more interested to carry on to watching. I was completely satisfied with the air battle moments! Coz it was extremely well made. Rain beautifully played his role; a funny guy with lots of talents as a pilot in air force squad! the other casts were also good in their parts but the only character that I was struggling with to empathy was Yoo Se Yeong which I think has been put in the story only to add some romance but I think that part was failed to achieve the goal coz it was somehow incomplete, Irrational and meaningless. For The music part, although I've watched this movie twice, couldn't fill any impressive music there to admire or maybe I was too focusing on Jeong Tae Hoon that didn't hear the music!(LOL) I'm trying too hard not to put any spoiler in my review but have to say this; that I couldn't understand why the pilots didn't use the ejection device on time to prevent the risk of loosing their life in jets. Generally I enjoyed watching R2B so much, It is a great movie and I hope that producers in Korea spend their money :p to made this kinda genre more! I recommend it highly to all of you to watch. Enjoy!
