The Unfortunate Problem With That '70s Show's Donna Pinciotti

Laura Prepon's Donna Pinciotti was of of the most important characters in That 70's Show. She may not have been as popular as Forman, Kelso, or even Fez, but her character was the backbone to what made That 70's Show so successful. That is, until the show's final season after Topher Grace and Ashton Kutcher left the series. That 70's Show took Donna and completely ruined her characters arc and the heart of the series.
