Even numbers are good, odd numbers are bad. Jonathan Frakes must have seen the pattern and decided that he better direct again, hoping that his success and superior directing power will prevail just like they did in First Contact . The Undiscovered Country and First Contact top it by far, and it is fairly close to some others, possibly below. However, it is not the worst, and is an enjoyable film to watch. A combination of good acting, humor, graphics, and action make it worth the while, even for non-Trekkie fans.
Insurrection has a simplistic complicated plot.
In itself, it's nothing exciting, but the writers put just enough turns in it to make it worthwhile. The political aspect of it was good, and the relationship between the Ba'ku and Son'a had good development. Unfortunately, there were a few of worthless and stupid scenes. It was just stupid. As for the conclusion, it was nothing spectacular.
