$40 and however many hours of prep just to play character after character who flees at the sight of any manifestation of merely learning the "secrets" of the campaign book? No thanks.
In my experience, players rarely spend hours preparing for a game. Sure, they have to think about their characters and actually roll them up, but it's the GM who does most of the preparation.
I guess if character attrition is really high then players might actually spend the "many hours of prep" that you mention, but that seems unlikely to me.
In any case, don't reject the game out of hand. At least play a round or two at a convention or demo just so you don't miss out on what may potentially be a good thing.
Call of Cthulhu is a lot of fun.
Trust me. I should know.
