You made this happen. You are the reason 25 years later we are still celebrating. So today we celebrate you as well. #wwbd." Marsters also reflected on the show's legacy on its anniversary.

Online USA/Getty "She had to deal with a lot of bulls--- on that show for all seven years it was on," Gellar's husband Freddie Prinze Jr. confirmed to the publication. "The stuff they pressed upon her, without any credit or real salary, while she was often the only one doing 15-hour days … yet she was still able to get the message of that character out every single week and do it with pride and do it professionally." Gellar noted, "I'm not the only person facing this, and I hope the legacy hasn't changed. I hope that it gives the success back to the people that put in all of the work. I will always be proud of Buffy. I will always be proud of what my castmates did, what I did. Was it an ideal working situation? Absolutely not. But it's OK to love Buffy for what we created because I think it's pretty spectacular."
