"Independence Day" definitely isn't "The War of the Worlds". The characters are all new, the alien invaders don't come from Mars, and HG Wells sure as hell didn't write about spaceships engaging in "Star Wars"-esque dogfights over Victorian England.
But here's the contradiction. "Independence Day" totally is "The War of the Worlds". It's about Earth being hopelessly outgunned by aliens from outer space and a human resistance fighting back against impossible odds. It also has, more or less, the same ending — the extra-terrestrials' demise by computer virus is a cunning update of the original book's microbial final twist.
