Seriously one the best,and most underrated,TV shows ever.
It's one of VERY few shows that I can't say one bad thing about at all.
From the first episode,right on through the last,BTVS was great,great TV; and every single episode was quality,and well thought out. All of the actors/actresses did a great job with their characters,particularly James Marsters (Spike),who does a great job of playing a smartass,kickass characters - while still putting on a realistic fake accent.
Also underrated from the show,another fantastic actor in the form of Anthony Head. He's really overlooked,and is great in his role,as well as his other projects (including his music).
Angel is also a good show.You can tell Joss Whedon puts a lot of work into his,well,work. The upcoming Angel episodes (the final ones) will be solid episodes,but if they would have had more notice of it's cancellation (which I STILL do not understand) they could have done more.
There is talk right now of future Angel TV movies,but nothing is definite right now.
Also,on a side note - I enjoyed the BTVS movie; it layed the foundation of the show,and tried to get as much into the movie as possible (which is what made it kinda "lame"). Plus,Kristy Swanson
and a cool cast like Rutger Hauer,Donald Sutherland,Luke Perry,a younger Hilary Swank,and Pee Wee (not to mention the greatest WCW Heavyweight Champion ever - David Arquette
)....
