Dimension 404 on Hulu is a science fiction anthology show in the tradition of The Twilight Zone and The Outer Limits. TV writer Andrea Kail loved the fifth episode, "Bob," about a (literal) giant brain who works for the National Security Agency. "I thought this was one of the best things I've seen in a long time," Kail says in Episode 347 of the Geek's Guide to the Galaxy podcast. "I thought it was incredibly good filmmaking, and incredibly great writing and acting. There was nothing about it I didn't love."

"Dimension 404" has been compared to "Black Mirror," but it seems the two shows may have more differences than similarities. "Dimension 404" and "Black Mirror" were both inspired by "The Twilight Zone," and they both tackle issues related to technology. For this reason, the two shows have been compared to each other, but they have a distinct difference. For one, Hulu's new science fiction drama is not as dark as Netflix's show. "Dimension 404" aims to give a lighter take on the science-fiction-horror genre.
