Well, there's no real plot to speak of, it's just an excuse to show some scenes of extreme violence and gratuitous sex (which can sometimes be fun, too, but it's not in this case). What else can I say about this...? The action, when happening, is inventive and there's a cool scene where two characters are falling from a skyscraper (one that has to be several miles high), but overall there's not much to recommend "Kite". Watch it if you want, but you're not missing much if you skip this one...
