Scooby-Doo 2: Monsters Unleashed turns 20, and James Gunn celebrates the occasion with a new social media post sharing his honest thoughts about the movie’s title. Released in 2004, the live-action Scooby-Doo sequel was directed by Raja Gosnell, with Gunn having written the screenplay. The film, which features Matthew Lillard as Shaggy, earned mostly negative reviews from critics, but was a success at the box office. Gunn would go on to write and direct movies like Slither, Guardians of the Galaxy, and The Suicide Squad.
