Such a good television series one of my favorites as a kid. Dustin Diamond was such a delight as Screech, Lark Voorhies as Lisa Turtle was perfection, Elizabeth Berkley as studious Jessie was a perfect casting, I couldn't imagine anyone else as Kelly besides Tiffani Thiessen, Mario Lopez as Slater was a solid fit, Mark-Paul Gosselaar as Zack was another great casting. Dennis Haskins serving as the lovable principal and adding that "adult" character was just what they needed. Leah Remini as Stacy, Leanna Creel as Tori, Tori Spelling as Violet and Bridgette Wilson as Ginger were great filler characters.
