"sir, we blew all our money casting action stars- we have no money to write a script!"
"don't worry- when you've got a movie like this, the plot is expendable"
Actually when they blew all their money on action stars, they had no money for good action scenes/CGI either. The first movie was terrible, and I do enjoy purposely mindless action movies but the gun fights and explosions were poorly done and too far apart to keep my interest. Go see The Raid: Redemption instead
