My advice is to go in with little knowledge of the story and if you find yourself bored or frustrated with the first couple of episodes, then strive through them and asses the series by ep 8. If by then your not enjoying the series, id suggest dropping it.
A choice i made years ago after only viewing the first 2 episodes. I put it on the back burner for 6-7 years..
My advice for all adult anime viewers - is to give this series a good shot. Its atmospheric and use of imagery, to tell the story, is something I've never witnessed done so uniquely in a anime. Its really something pretty special. Try to watch in the best quality possible too.
