This is what we want. Contrast. A bit of both. Happiness and sadness. Light and dark. A balance of both so that the viewers keep watching. Now avid Buffy fans will know that that is what was produced with every season.
But season five is considered the point at which the writers of Buffy truelly found themselves. Storylines became deeper and more moving, and no story seemed too rushed.
This is what kept me watching, along with the intelligence that came into the main plot of season five. We are introduced Buffy's 14-year-old sister Dawn, a shock as:
(a) Buffy was, before this point, referred to as an only child on many an occasion, and...
(b) those around Dawn treat her as though she has always been there.
But this strange appearance does not come without a thorough and enthralling storyline, as Buffy and the rest of the Scooby Gang find out in this season.
It would be silly of me to say the obvious. "Great, shocking, must-see TV" etc.
Instead, I'll say that Season five is one of the best in the series. It's a solid reason for the show to make new fans as well as keep the old ones.
Finished or not, Buffy remains today one of my favourite TV shows.
