Netflix's "Chilling Adventures of Sabrina" is definitely not a remake of "Sabrina the Teenage Witch."

The streaming service got the stars of the '90s sitcom to watch some of "Chilling Adventures of Sabrina," starring Kiernan Shipka, and a new video shows their reaction. Let's just say it was a little shocking for Melissa Joan Hart (Sabrina), Nate Richert (Harvey), Caroline Rhea (Aunt Hilda), and Beth Broderick (Aunt Zelda). They saw firsthand that the Netflix series is much darker and more adult.

Hart and Richert watched as a pair, as did Rhea and Broderick, and both twosomes found themselves freaked out by scary scenes. They also were entertainingly shocked by some of the more mature content, such as onscreen kissing and clothes being removed.

"This is not our Sabrina!" Rhea joked at one point.

Their observations are pretty funny. Watch the full video below.

"Chilling Adventures of Sabrina" Season 1 is now available on Netflix.
