My favorite so Far , but...(Spoiler)

Rating: 8/10 (18 January 2012)

OK this is the first time I've seen an MI movie without feeling like something was lacking. The plot was good, the little expressions of comedy and the overall feel, all good. It did not present a great remember-able villain, but at least it gave it time to focus more on the hero cast. Now for the but... There is a plot hole here so huge i could park a DC10 in it, there is a major part of the plot revolving around launch codes. The MI agents have a device which scrambles the numbers, they make fake copies and give them to the bad guy, they can trace the copies since they have an isotope on them. So the bad guys get away with the Fake copies, they never know or see the real launch codes but are being chased by the heroes as if they do, and then use the fake codes to launch a missile. How do they do this????
