Wireds Jason Silverman ranked Interkosmos alongside Automatons, Puzzlehead, and The Wild Blue Yonder as "Best Shoestring Sci-Fi of 2006" stating that "At times, Interkosmos''' hip, deadpan style threatens to grow tiresome, but then Finn injects something unexpected to liven it up. By the end, Interkosmos'' has coalesced into a colorful portrait of an imagined time where movies and space travel were happy, bubbly things."
Jason Silverman from Wired praised Interkosmos for its distinctive style and capacity to balance humor and excitement, ultimately creating a vibrant and imaginative film that captures the joy and optimism of an idealized era.
