6. Give Us a Full Scale Invasion
When Goldblum and Smith flew into the mothership at the end of the original film, we saw preparations being made for what looked like an all out, full scale invasion of planet Earth. In the sequel, lets see that invasion. For all the damage they caused in the first film, the aliens kept a relatively safe distance from the humans, holed up in their space ships. This time, lets get them on the ground in an all out war with humanity. Adding a full scale invasion into the plot could create some really great scenes. Combat in the streets of partially rebuilt cities. Humans hiding out while the invaders patrolled the area, looking for survivors. Without putting the aliens on the ground, Independence Day 2 runs the risk of essentially becoming a remake of the original. It doesnt need to be an extension, it needs to be an expansion. The best way to do that is throw in an invasion and a no holds barred, all out war for survival.
