What I Learned from This Movie
1. Whenever the government has a major disaster with a scientific project, the director of the project will turn out to have been involved with one of the scientists who left the project due to ethical differences.
2. Scientists who leave black box government projects and write a science fiction book directly based on their work will not suffer any consequences if their ex-wives are the project directors.
3. Despite ample time and experience with which to figure out that a 5.56mm assault rifle is not going to be very effective against the carnivorous creatures from the future, the military will not issue higher-caliber weapons to the soldiers in the time machine lab or the ones heading into the future to fight the creatures.
4. When your time machine is damaged and stranded in a hostile future and threatens to destroy the present, you should send the only guy who knows what's wrong with it into the future rather than have him write down the solution for you ... or even have him leave some notes behind.
5. When you're trapped in a cage by Morlocks and find a way out, you should wait for your ex-husband to find you before you actually climb out of the cage.
