Awesome but with little flaws

Rating: 10/10 (21 June 2014)

I love this movie, I didn't see the old James Bond movie, though, but I can tell it followed the old fashion ways of the old franchises.
However, just a little question, those bad guys, they are trained troopers, and well-organized. What on earth makes them think of spending tons of money on bullets but one bloody missile? I mean, you can get a chopper...I don't see why can't you buy a freaking missile to just blow the house away and kill "three old pieces". I mean two of them could barely run, and the last one can't hold the gun firmly( even though somehow he can make the good shots at the last gun fight). So just saying, you should make the movie more logical.
