No. Buffy is probably one of the best and most important genre shows of it's era. Complaining about the limitations of CGI on cable television in the late 90's is about the lamest critique you could ever have imo. You are talking about something that is closing in on a quarter of a century and had to fit that CGI budget with 22 episodes of other effects needed for the season.

Anyways Buffy pretty much perfected the 22 episode genre television format. It pioneered a bunch of themes that weren't being touched upon in mainstream entertainment at the time and constantly was pushing the boundaries of the show and experimenting with different styles.

It's also not really a secret that the biggest movie franchise in the world is basically using Buffy style dialogue for all it's films now because the showrunner directed one of the most successful films in the series and they decided that's how everyone is going to talk and react now. Buffy speak is now Avengers speak.
