No reason to continue squandering brain-spit chewing on the idea of what a modern-day sequel to E.T. the Extra-Terrestrial might look like. We've got it. This is it. These guys nailed it with this trailer for E.T.-X (aka E.T. Extinction).
Spliced together from clips of Henry Thomas movies you didn't know existed and other relevant films, the fake preview sees E.T.'s alien race returning to Earth 30 years after their first visit---only this time they're invading! And they're vampires? I think they're alien vampires. Thankfully, our side has got Gen. Morgan Freeman, Bruce Willis, Original E.T., and Elliott's knowledge of extra-terrestrial candy love, so you can see how this is shaping up to be a pretty good battle. Anyway, just watch. So good. And likely prescient.
