Many film producers begin to shoot, or continuously shoot all the movies in a series at one time (such as LotR if I remember right). Saw doesn't generally begin production until after a movie is released, which means they have *maybe* a year to put together an entire movie, where most blockbusters and highly rated movies take 1 1/2 - 2 1/2 years.
Pwned, lol. And yeah what dem said is correct, the more time they put into making a film, the more they will concentrate on all of the parts and the more they concentrate the better output they will get. All in all, more time = a-w-e-s-o-m-e-n-e-s-s.
Does the releasing of a sixth movie really trouble you that much? You're not going to be strapped to a chair and forced to watch them, so you don't have to whine about it. Oh and by the way, if you haven't noticed... all movies are telling parts of a story. It's one huge story arch.
I'll wait til it comes out on netflix. The first 5 were good but yeah how far can they really go with this.
