South Park, while incredibly controversial, is definitely one of the most popular and influential animated shows of all time. Due to its crude animation style, it appeals to a large audience who are often swayed away from animated shows or films because of how complex they try to be. The show follows four young boys and their odd and surreal antics through day-to-day life.
One of the most interesting things about South Park is that the creators, Trey Parker and Matt Stone, made the pilot episode entirely using cut-out animation. This episode took the longest time to make, so all the episodes since then were created using computer software which imitates the style of cut-out animation. They both stated that they chose to continue with the cut-out animation style as they liked how unique it looked, due to the different body parts being moved accidently and adding a jumpy style of movement.
One of their main influences for the show is actually the work of Terry Gilliam, who created most of the animation for Monty Python. The creators state that as they were life-long fans of Gilliam’s work, they always wanted to create something similar to what he created, and when they had the opportunity to make South Park they could not turn it down.
