Plus, the end and the beginning just don't match. At the beginning of Ghost Protocol, we're tasked to believe that Ethan Hunt is now so far advanced in his skills that he can casually make a prison break whacking several guards in the process. At the end, we're tasked to believe that the same arrogant cuss is getting the crap beat out of him by a scientist.
The whole movie felt like a satire of the franchise.
