...and here's why:
1) The plot is an overlong, unengaging mess
2) The action scenes are generic (mostly shootouts in which it's often hard to tell who's shooting at whom, and special effects-enhanced explosions).
3) The fight scenes are brief and overedited. There is one girl (Grace Yip) that appears to be a better fighter than the three male leads, and where is she during the climactic fight? Nowhere to be seen!
4) 15 years after the "Lucky Stars" series, Eric Tsang is still providing the same kind of lame-brained "comic relief". Isn't it time for this guy to give it a rest?
Two spectacular sky-diving sequences are all I'll remember from this one...and yes, it's easy to see why the very handsome Nicholas Tse has so many female fans.
