Buffy The Vampire Slayer and The Walking Dead

I am looking forward to the new season of The Walking Dead hitting the airwaves in a few weeks.  I have been watching the prequel series Fear the Walking Dead, And while it has a talented cast, I do not find it nearly as exciting as the main show.  The idea of showing how the zombie outbreak began is an intriguing one, but by concentrating on such a small group of characters, the series lacks the kind of scale which  that story really demands.
