Seinfeld was a highly successful show of the 1990s, with consistent writing and acting that kept fans engaged for nine seasons. The show featured memorable guest stars, but Heidi Swedberg's character, Susan, caused friction on set due to her lack of chemistry with the main cast. Many found it difficult to work with her, which ultimately led to her character being killed off. Despite this, series creator Larry David insisted her character was perfect for the show.
