Roger Joseph Ebert (June 18, 1942 – April 4, 2013) was an American film critic, historian, journalist, screenwriter, and author. He was a film critic for the Chicago Sun-Times from 1967 until his death in 2013. In 1975, Ebert became the first film critic to win the Pulitzer Prize for Criticism. (Wikipedia)
Considering this was directed by a guy whose only film at the time was Piranha II: The Spawning. It seems like a miracle.
