I'm glad you did. Keep in mind there are two different routes with two very different styles (Transmitter & Placebo chapters), so even if you didn't like one, you could like the other. You should do them in succession, like chapter 1 Transmitter > chapter 1 Placebo, and so forth. They complement each other, so even if one chapter appears inscrutable, the other chapter is going to make the picture clearer.
You just gotta commit that you're not supposed to understand everything right off the bat. Like a thriller, the author holds the cards, and decides when to put them down regardless of expectations.
