It would have worked better if the villain wasn't ultimately so cartoonish. Instead of blowing up Earth, if his objective had been more subtle, more nuanced.
My take was that the destruction of Earth wasn't one of Shizon's priorities. Rather it was a promise he made to the Romulan military in exchange for their co-operation, the Simitar could only be in one place at a time and Shizon needed the Romulan military to control the empire. Failure to live up to his promise relatively quickly would result in the military turning on him.
