Fans tuning into South Park season 25 were left puzzled by the short 6-episode run. South Park has never been a typical television show, from the fact that the series began life as a viral email Christmas card to its boundary-pushing content (and shockingly swift production schedule), South Park is risky in terms of most television traditions. The risqué animated satire is currently on its 26th season and has one theatrical movie but, in its time on air, South Park has been protested, praised, challenged, awarded, and banned in equal measure.
