The show - which aired originally on The WB and later on UPN from 1997 to 2003 - was featured in the list compiled by Yahoo! to mark the releases of TV to film adaptations Sex And The City 2 and The A-Team.
Following the 1992 feature film starring Kristy Swanson, Sarah Michelle Gellar played vampire slayer Buffy in the hit television series, which was described as "relatable, real, ridiculously clever, and just good old-fashioned fun".
Other adaptations in the list included long-running television spinoff M*A*S*H, which followed the 1970 film, and Stargate SG-1, which picked up where 1994 movie Stargate left off.
Friday Night Lights and Parenthood also made the list.
