The entire plot of the movie is a hole.

Rating: Null/10 (9 November 2009)

The Romulan commander jumps through time in various points to no less than destroy Vulcan, hunt down Spock, and attempt to destroy Earth... all driven by his rage over losing his family do to a solar disaster that destroys Romulus... am I right so far? Why doesn't he just simply go back and return to Romulus before the disaster to either save just his family or perhaps warn the entire planet? It was after all a natural occurrence that destroys Romulus. Other than the general plot suffering from this glaring question, the movie is a great action flick that loses the "two hour episode of Next Generation" many previous Star Trek movies tended to suffer from.
