Actually, the more I think about it, the prequel sounds like the better show. I might even check the premier out (Aug. 23rd).
There are probably not so many zombies. I believe it's about the origins of the zombie epidemic so it probably just starts with mysterious hints of zombie-ism in each episode. Maybe an isolated zombie here and there. Not just big packs of zombies everywhere.
While it wasn't my only problem with the Walking Dead, a big problem was I find zombies to be terrible characters. So large packs of them are large packs of terrible.
An origins series? Ehhh, probably not but maybe.
