I can't believe you typed that...
Shinzon does not gain control of the Romulan Empire without the help of Romulans. You can do all the backwards somersaults you want to work around it. It simply doesn't happen.
Riker even says in the movie that the praetors power has always been the Romulan fleet. Shinzon does not take control without the support of the fleet.
Early in the film, they're on the right track. They paint this image of Shinzon being this cunning, cold warrior who takes control of the Empire. But they present us a pimply nerd who is infatuated with Troi's hair and wants to have tea with the brother who had a better life than he did.
Shinzon rising to power isn't the problem, it's the fact that the character we see doesn't match the character we are told about.
