Pretty decent actually
Of course you've seen this concept before.
Howver, even if you have the film is very snappy and puts up some good chase sequences that will make you grab onto your seats.
Not something you'd watch again but it's actually fun while it lasts.
Didn't quite bust blocks in Korean box office, it is still worth a look.
Thumbs Up, Thumbs Down and a Wagging Finger of Shame
