"L5" is a crowd-funded independent miniseries premiering later this month. It centers around the crew of a manned mission to Barnard's Star. When they return to earth they find 200 years have passed and there's no sign of life anywhere on the planet.
After Earth looks kind of cool, but it's directed by M. Knight Shyamalan, so it will likely be massively disappointing. On the plus side, a new Shyamalan movie means it's time to play "Guess the Twist!" What do you think it will be?
My guess is Shyamalan will "borrow" from older, better sci-fi and this will actually be the story of how humans colonized pre-historic Earth, making the title of the movie almost completely meaningless. What a twist!
