First let me say: This is a very FUNNY, enjoyable film!
Great plot, funny ideas and well executed in all points. A good laugh akin to those in most black comedies.(I.E. Heathers, Doubles and Big Bully)There's a little 3 stooges mixed in as is commonly found in most asian comedies, but 95% is just dark humor and fun!

Second,I must say this: Warning!
I ordered a copy of Attack the Gas Station from Amazon and much to my utter dismay, it was DUBBED in Cantonese and Mandarin with no Original KOREAN track available! Also, there was no indication of this on the back of the DVD box, so I had to open it, to find out what the audio and subtitle tracks were and thusly by opening it, made it impossible to return to Amazon. So be careful when you buy this movie. Make sure you know what you are getting. At least the print is Widescreen, so one out of two ain't bad. But I just can't see watching this great Korean Film DUBBED! To truly get the LAUGHS, you have to watch it in the original language!
