Ultimately I think that if the movie started off with a better reason behind the whole event being insubordination it would've been a lot stronger. I would've liked to have seen Topher Grace's character and the project strongman characters built up and expanded a bit more. Not to mention extending the action scenes a bit more. All the good stuff happens the last quarter of the movie. I think these few changes would've made the plot a lot stronger, but it could've been a budget thing. They obviously don't intend to turn this into a series, much more just a one off thing.
