Mark Hamill is narrating a Hulu show all about internet horrors

"I'm sorry viewer, the TV show you're searching for cannot be streamed in your reality. Please stand by for reconnection." Those are the opening lines of Hulu's new show Dimension 404, a show that explores "the wonders and horrors of our digital age" in six one-hour episodes. If that makes you think of Black Mirror, you're not alone. But Dimension 404, which debuts on April 4, is not as similar to the BBC series (which Netflix distributes in the U.S.) as you might think.
